Abstract

The Online Information and ordering System for Pacla Hydraulic House is primarily

designed to lessen the consumption of time and effort spent on the part of the customers and

employees. This will increase the number of customers improve order accuracy and have a

lucrative business. But before the development and design of the proposed system, the

proponents had chosen a methodology as a basis in developing the proposed system.

The proponents used 4th

Generation Technique or 4GT. During the first stage, the

proponents used different methods in generating data such as interview, observation and survey.

During the next stage - On design strategy, the proponents created Context Flow Diagram

(CFD), Data Flow Diagram (DFD), Entity Relationship Diagram (ERD) and Hierarchical Input

Process Output Chart (HIPO Chart) to show the flow and process of the transaction in Pacla

Hydraulic House and to illustrate how the database is being normalized as well as the

relationship of the tables to each other through the use of the graphical design. On the third stage,

the proponents had implemented the technical specification of the proposed system using 4GL.

Lastly, the testing phase focuses more on testing the overall performance of the proposed on-line

system to Pacla Hydraulic House to identify if the system meets the requirements in terms of

inputs and outputs.

The host company will benefit a lot in the completion of the system. In line with this, an

employee would not be preparing reports manually or even retrieving it anymore. Customers can

freely inquire about the products and services offered by Pacla Hydraulic House. Through this,

Pacla Hydraulic House will no longer use a manual system but a computerize one. In addition, it

will expand its market globally at reach a large number of people.

Preface

Pacla Hydraulic House specializes in all kinds of hydraulic and industrial hose, hydraulic

fittings, fluid power piping system and components, power steering, quick coupler, o-rings and

hydraulic oil and greases. With the wide range of experience on marine and industrial companies

and engineering projects, Pacla Hydraulic House was established to facilitate the present demand

in technological works. However, the hydraulic company is having difficulties in entertaining all

their customers due to the slow-processing transaction caused by the manual system. To avoid

this problem in the near future, the system developers had designed and developed an on-line

information and ordering system for Pacla Hydraulic House.

This five-chapter documentation contains various explanations and discussion of the

proposed system.

Chapter 1 – Introduces the general problem that the proposed system addresses as well as the

importance of accomplishing the on-line system. This also states the current state of technology,

the specific ends or objectives of the proposed system, the scope and the limitation.

Chapter 2 – It contains the correlation of the different theories applied by the proponents.

Chapter 3 – Contains an explanation on how the system is put together, through the use of

graphical design tools like Context Flow Diagram, Data Flow Diagram (DFD), Entity

Relationship Diagram (ERD) and Hierarchical Input Process Output Chart (HIPO).

Chapter 4 – The performance Analysis, describes the experiment conducted in analyzing the

performance of the proposed system base from the parameter indicated on the survey forms.

Chapter 5 – Concludes the overall on-line system, the output of the performance analysis and

recommendations.

The proponents developed an on-line information and ordering system for Pacla

Hydraulic House. In addition to this, the system will offer on-line ordering of items. An on-line

ordering catalog will be likewise provided to display the products and it will have a request for

quotation. The system will also feature a search engine module for easy browsing and locating

specific products. Shopping cart software will be added in the system to assist customers in

making on-line purchases and an inventory management will as well be implemented for easy

and fast monitoring and updating of Pacla Hydraulic House’s items. With the use of the system,

customers will no longer consume a lot of time and effort take in placing orders than the usual

way of ordering. The system will help the employees prepare required reports for the

management as well. The firm will expand its sales, marketing and will provide a faster and

more accurate processing of transaction, such as advertising the products and ordering in an

organized manner.

An On-line Information and Ordering System for Pacla Hydraulic House 1-1

Chapter 1 INTRODUCTION

The World Wide Web (commonly shortened as web) is a system of interlinked

hypertext documents accessed via the Internet. With a web browser, user views web

pages that may contain text, images, videos, and other multimedia and navigates between

them using hyperlinks [WIKI2008].

The Internet, sometimes called the “Information Superhighway”, is a worldwide,

publicly accessible series of interconnected computer networks that transmit data by

packet switching using the standard Internet Protocol (IP). It is “network of networks”

that consists of millions of smaller domestic, academic, business, and government

networks, which carries various information and services together, such as electronic

mail, on-line chat, file transfer, and the interlinked web pages and other resources of the

World Wide Web (WWW) [WIKI2008].

An Information System (IS) is the system of persons, data records and activities

which process the data and information in a given organization, including manual

processes or automated processes. Usually the term is used erroneously as a synonym for

computer-based information systems, which is only the Information technologies

component of an Information System [WIKI2008].

Electronic commerce is the paperless exchange of business information using

electronic data interchange (EDI), e-mail, electronic bulletin boards, fax transmissions,

and electronic funds transfer. It refers to Internet shopping, on-line stock and bond

transactions, the downloading and selling of “soft merchandise” (software, documents,

graphics, music, etc.), and business-to-business transactions [BUSI2008].


On-line ordering services are websites that features interactive menus allowing

customers to place orders with local host. Much like ordering consumer goods on-line,

any of these allow customers to keep accounts with them in order to make frequent

ordering convenient. On-line ordering system will give the customers the availability to

place orders on-line, as well as view and print your entire menu 24 hours a day, 365 days

a year [WIKI2008].

A Transaction Processing System (TPS) is a type of information system. Which

collects, stores, modifies, and retrieves the transactions of an organization. A transaction

is an event that generates or modifies data that is eventually stored in an information

system [WIKI2008].

A website with an on-line ordering system includes the distributing, buying,

selling, marketing, and servicing of items. Through the use of on-line ordering, the

company may expand its market, sales and services to their customer and will also make

the transactions faster and more accurate. The Pacla Hydraulic House (PHH), a sole

proprietorship owned and managed by Capt. Conrado T. Pacla, was organized and began

its operation on December 1995.

With a wide array of experience on Marine and Industrial Companies and

Engineering Projects, PHH was established to support the present demand in

technological works. The present technology in the fields of hydraulic system, as well as

in the range of industrial plants and other machineries, uses hoses.


1.1 Statement of the Problem

How will the proponents design, develop and implement an On-line

Information and Ordering System for Pacla Hydraulic House in order to

computerized its current business system?

The Pacla Hydraulic House offers their customers a network of six (6)

commercial offices located in the City of San Fernando, which serves as its main

office. The other offices include Balanga City, Guiguinto Bulacan, Angeles City,

Tarlac City, and Olongapo City. An efficient logistic and technical service is also

assured through the brand hoses and the fittings which are used. These hoses and

fittings are imported with brands made in U.S.A, Japan, Italy and Germany which are

certified with either International Standard Organization (ISO) 9001 or ISO 9002,

giving further evidence of the hydraulic group attention to quality. In addition, the

high performance level of these products is also confirmed by certifications received

from some of the most important original equipment manufacturers and type

approvals for mining, naval and military applications (Germanischer Lloyd, Det

Norske Veritas, Bureau Veritas, etc.)

Currently, the company depends only on walk in customers and phone calls

orders, sometimes the sales representative goes to their clients to get orders and

introduce to them the new items the company sells. They use MS Excel for the

template of invoice and receipt. They monitor the orders and the product sold by

using a piece of paper or a log book in listing products.

An on-line ordering system for Pacla Hydraulic House will be designed in

order to expand its marketing. This system can be used to purchase fabrication of all


kinds of high pressure hydraulic assembly hoses, industrial hoses, fluid power piping

system and components, hydraulic fittings and make frequent ordering convenient.

User friendly index and search functions are provided to locate products quickly.

Orders can be placed anytime twenty four hours a day, seven days a week.

Sales representatives are responsible for promoting or introducing their

products to different clients. The sales representative personally goes to clients, like

corporations and constructions corporation firms, to be able to introduce or discuss

the products. This system consumes a lot of time and effort for the company

especially on the part of sales representative because they need to discuss every

product and its information and sometimes there are clients who are not interested

with the product being offered.

The use of the current system takes a lot of time and effort in terms of ordering.

Some customers personally visit the company or they place orders over the phone. An

employee lists down orders and products sold by using a piece of paper or a log book.

The company has various items. Because of this, there would be lots of records

to manage. An employee consumes a lot of time and effort because they need to count

the stock manually then store the records in a file cabinet. There is a possibility to

commit and encounter errors using manual counting.

It takes a lot of time and effort to search for specific products that are stored in

the file cabinets. If a customer wants to look for a particular product, he must

personally ask an employee of the company. The current system does not have an

efficient database to store all information about the products.


Company’s representatives consume a lot of time and effort in making

different kinds of reports like Sales Reports, Inventory Reports, Order Reports, Back-

Order Reports, Delivery Reports, Adjustments Reports, and Stock Reports. All of

these reports could tell the status of the products and the transactions made by both

the company to their supplier and the customers to the company, as well as the

standing of the company.

The current system does not have a security module to secure the important

files stored in computer and file cabinet. Alteration and tampering of records without

the consent of the management could happen, since those computers and filing

cabinets are accessible to anyone.

1.2 Current State of the Technology

Pacla Hydraulic House specializes and services all kinds of hydraulic and

industrial hose, hydraulic fittings, fluid power piping system and components, power

steering, quick coupler, o-ring and hydraulic oil. It promotes and advertises items by

having their representatives visit different corporations and construction companies in

their areas of concern, referrals, and/or word of mouth. They also visit or call the

companies to take orders. The company accepts cash or checks only. Once the order

is approved, it is then delivered to the customer or the customer personally picks up

the ordered items. In the event that a customer wants to cancel, return or exchange his

orders, he may do this either through phone call or via sales representative. Other

customers personally visit the office of Pacla Hydraulic House to do those

transactions. One of the three copies of the invoice receipt will be left to the

customer, and then the two will remain to the company for record keeping purposes.


The inventory clerk manually counts the incoming and outgoing products daily. After

counting the products, the representative will list down all the number of products

sold and backed in a piece of paper. The company uses logbook or any paper of its

form to record it. The cashier will input the data into the computer using MS Excel,

make a hard copy of the inventory and store it into the file cabinet. The current trend

of on-line ordering system gives complete details and records for the items; it

provides good advertisement and marketing. With its convenient way of ordering

with efficient inventory, it also shows item features.

The proponents had searched for any existing system which is similar to what

the proponents intend to design, develop, and implement. They had discussed the

features of those existing system being used by various firms and the features the

proponents intend to incorporate or even to improve on their proposed web

application.

Alfagomma has the usual Homepage which includes navigational menus like

home, company’s history, contact us, products and catalogues. Their product

catalogue can be browsed on the web, wherein you can browse their whole product

range, selecting the section you are interested in and visualizing the product

datasheet. Part of the catalogue sections you will find the request for quotation

wherein you can browse the product by clicking on the item code. Fill out the pop-up

form that will appear with the information and they will be glad to answer it as soon

as possible [PIXE2003].

M – Tech Supply provides fabricating equipment for people who demand

quality at an affordable price. It has this shopping cart to assist people making


purchases on-line. It allows on-line shopping customers to place items in the cart

[MTEC2008].

Truck trailer parts and on-line superstore has a catalog which contains every

part available on their website in one easy-to-use format. Browse the part you need,

search for the part and place the customer order on their website [TRUC2008].

The proponents intend to develop an on-line information and ordering system

for Pacla Hydraulic House. The proposed system will offer on-line ordering of items.

An on-line ordering catalog will be provided to display the products and it will have a

request for quotation similar to what Alfagomma and Truck Trailer Parts and On-line

Superstore have. The proposed system will also feature a search engine module for

easy browsing and locating specific products. Shopping cart software, like on M –

Tech Supply, will be added in the proposed system to assist customers in making on-

line purchases and an inventory management will as well be implemented for easy

monitoring and updating the items of Pacla Hydraulic House. With the use of the

proposed web application, customers will take lesser the time and effort in placing

orders than the usual way of ordering. The system will help the employees prepare

required reports for the management as well. The company will expand their sales,

marketing and will provide a faster and more accurate processing of transaction, such

as advertising the products and ordering in an organized manner.


1.3 Objectives

1.3.1 General Objective

To design, develop and implement an On-line Information and

Ordering system for Pacla Hydraulic House in order to computerized its

current business system.

The proponents aim to develop a website that allows on-line ordering of

items and design an inventory management for monitoring and updating the

inventory items of Pacla Hydraulic House to lessen the consumption of time and

effort spent on the part of the customers, employees and owner in doing the said

business processes.

The company will increase the number of customers due to the on-line

information and ordering of items. It will have a profitable business. Also, it

will give the company and the customer an on-line advertisement which would

attract more customers. The system will be convenient and efficient to the

customers and employees who will use the system because there are some

features which will provide the information automatically. It will provide an

easier way of ordering, cancelling, and inquiring as well.

1.3.2 Specific Objectives

To design, develop and implement an on-line catalog that will

display the information of the products of Pacla Hydraulic House.

The proponents will develop a system that will have an on-line

catalog for advertising the products. The customers can view the list of

items offered by the company. The said system also provides sufficient


information about the items of Pacla Hydraulic House. This is for the

benefit of the representatives because they no longer need to go to the

clients to promote and discuss the items.

To design, develop and implement an on-line ordering module

that will allow their customers to place their orders.

The proponents will develop a system that includes an on-line

ordering module. This will allow the users to perform the ordering process

on-line that will lessen the time of the transaction. The process will also be

convenient for the client because they could choose from the list of

catalogues and make order anytime and anywhere using his computer.

To implement an inventory management that will easily

monitor and update products.

The proponents will develop a database for different item files

such as description and information of the items, customer information,

orders and inventory references. This system will organize those

records/files through the computer and would give more convenience for

the said person. It would also monitor the availability of the products to

avoid out-of-stock as well as over-stock items.

To design, develop and implement a search module that will

efficiently locate specific products.

The system will provide a search module for easy searching of

products without consuming a lot of time and effort for the clients. Both the

back-end and the front-end have its own searching module.


To design, develop and implement a module that will generate

faster, more reliable and timely reports.

The generation of faster, more reliable and timely reports made by

the company will be provided on this module. It will generate a report

using the information on the transactions made by the company and

customers that are stored in the database.

To design, develop and implement a security module that will

secure the file and prevent the access of the unauthorized personnel.

The system will provide a security module by using different levels

of access to prevent the access of the unauthorized personnel. Only

authorized personnel can access confidential records. This is to ensure that

all records will be secured.

1.3.3 Scope and Limitations

The proposed system for Pacla Hydraulic House will cover the

following for the front end and back end:

Scope

This module will be used by the customer in placing an order.

Now, even beyond normal working hours, a customer can place an order, or

even outside the business firm, they can transact. This helps to speed up the

transaction between the customer and the company and lessens errors of


order’s details. Orders then will be more well-organized and well-detailed.

This will save time, money, and effort in the part of the customer.

o On-line Products Catalogues

The website will provide two (2) catalogues, direct ordering and

request for quotation, which contains the list of product’s price and its

description. The direct ordering catalog contains products which has a fix

price. The second catalog will contain products that are subject for

quotation, such as hoses and fittings with service.

o On-line Customer Registration

It will have a registration form that the customers must fill out

An On-line Information and Ordering System for Pacla Hydraulic House 2- 1

Chapter 2 THEORETICAL FRAMEWORK

2.1 Introduction

The term “theory”, is an accepted principle, assumption and rules of

procedure based on the limited information or knowledge, devised to analyze, predict

and abstract reasoning that the proponents use in the development of the proposed

system for Pacla Hydraulic House.

2.2 Internet

Internet is composed of many interconnected computer networks. Each

network may link tens, hundreds or even thousands of computers, enabling them to

share information and processing power. The Internet has made it possible for people

all over the world to communicate with one another effectively and inexpensively.

Unlike traditional broadcasting media, such as radio and television, the Internet does

not have a centralized distribution system. Instead, an individual who has Internet

access can communicate directly with anyone else on the Internet, post information

for general consumption, retrieve information, use distant applications and services or

buy and sell products [ENCA2008].

2.3 World Wide Web (WWW)

World Wide Web (commonly shortened as the Web) is a system of

interlinked hypertext documents accessed via the Internet. With a Web browser, a

user views Web pages that may contain text, images, videos and other multimedia

and navigates between them using hyperlinks [WIKI2008].

2.3.1 Website

Website (alternatively, web site or Web site, a back-construction from

the proper noun World Wide Web) is a collection of Web pages, images, videos

or other digital assets that is hosted on one or more web servers, usually

accessible via the Internet. A Web page is a document, typically written in

(X)HTML, that is almost always accessible via HTTP, a protocol that transfers

information from the Web server to display in the user's Web browser

[WIKI2008].

2.3.2 Web page

Web page is a resource of information that is suitable for the World

Wide Web and can be accessed through a web browser. This information is

usually in HTML or XHTML format, and may provide navigation to other web

pages via hypertext links.

Web pages may be retrieved from a local computer or from a remote

web server. The web server may restrict access only to a private network, e.g. a

corporate intranet, or it may publish pages on the World Wide Web. Web pages

are requested and served from web servers using Hypertext Transfer Protocol

(HTTP).

Web pages may consist of files of static text stored within the web

server's file system (static web pages), or the web server may construct the (X)

HTML for each web page when it is requested by a browser (dynamic web pages)

2.4 Graphical User Interface

A Graphical User Interface (GUI) is a display format which enables the user

to choose commands, start programs and see lists of files and other options by

pointing to pictorial representation, called icons, and lists of menu items on the screen

or user interface. Choices can generally be activated either with the keyboard or with

a mouse. Modern GUIs are used on the Macintosh operating system, Microsoft

Windows, and the OS/2 Presentation Manager.

For application developers, GUIs offer an environment that processes the

direct interaction with the computer. This frees the developer to concentrate on the

application without worrying about the details of screen display, mouse control or

keyboard input. It also provides programmers standard controlling mechanisms for

frequently repeated tasks such as opening windows and dialog boxes. Another benefit

is that applications written for a GUI are device-independent: as the interface changes

to support new input and output devices, such as a large-screen monitor or an optical

storage device, the applications can, without modification, use those devices

[ENCA2008].

2.5 Wide Area Network

Wide Area Network (WAN) is a computer network that is meant to cover a

wide geographic area, usually over telephone lines, as compared to a local area

network that operates in a single company or institution. The Internet is an

interconnected web of wide area networks [ENCA2008].

http://encarta.msn.com/encyclopedia_761554135/Presentation_Manager.html


2.6 Local Area Network

Local Area Network (LAN) is a collection of interconnected computers that

can share data, applications and resources, such as printers. Computers in a LAN are

separated by distances of up to a few kilometers and are typically used in offices or

across university campuses. A LAN enables the fast and effective transfer of

information within a group of users and reduces operational costs [ENCA2008].

In contrast with the wide area network, LAN spans a relatively small area.

The proposed on-line information and ordering system will as well be implemented in

a local area network. Computers at the office will be networked locally. There is no

need for an employee to go to the other computer, for example the computer being

used by the manager or administrator, to access the system. He can access directly the

system on the computer provided for him in the office.

2.7 Hypertext Transfer Protocol

Hypertext Transfer Protocol is a communication protocol for the transfer of

information on the Internet. Its use for retrieving inter-linked text documents

(hypertext) led to the establishment of the World Wide Web.

HTTP is a request/response standard between a client and a server. A client

is the end-user; the server is the web site. The client making an HTTP request - using

a web browser, spider or other end-user tool - is referred to as the user agent. The

responding server - which stores or creates resources such as HTML files and images

- is called the origin server. In between the user agent and origin server may be

several intermediaries, such as proxies, gateways and tunnels. HTTP is not

constrained to using TCP/IP and its supporting layers, although this is its most

http://en.wikipedia.org/wiki/Gateway_%28computer_networking%29

http://en.wikipedia.org/wiki/Tunneling_protocol

http://en.wikipedia.org/wiki/Internet_protocol_suite


popular application on the Internet. Indeed HTTP can be "implemented on top of any

other protocol on the Internet or on other networks. HTTP only presumes a reliable

transport; any protocol that provides such guarantees can be used [ENCA2008].

2.8 File Transfer Protocol

File Transfer Protocol is a network protocol used to transfer data from one

computer to another through a network, such as the Internet.

FTP is a file transfer protocol for exchanging and manipulating files over

any TCP-based computer network. A FTP client may connect to a FTP server to

manipulate files on that server. As there are many FTP client and server programs

available for different operating systems, FTP is a popular choice for exchanging files

independent of the operating systems involved [ENCA2008].

2.9 Multimedia

Multimedia is the presentation of information using the combination of text,

sound, pictures, animation, and video. Common multimedia computer applications

include games, learning software and reference materials. Most multimedia

applications include predefined associations, known as hyperlinks that enable users to

switch between media elements and topics [ENCA2008].

Multimedia represents the convergence of text, pictures, video and sound

into a single form. The power of multimedia and the Internet lies in the way in which

information is linked. Multimedia and the Internet require a completely new approach

to writing. The style of writing that is appropriate for the “on-line world” is highly

optimized and designed to be able to be quickly scanned by readers. A good site must

be made with a specific purpose in mind and a site with good interactivity and new

http://en.wikipedia.org/wiki/Network_protocol


http://en.wikipedia.org/wiki/Transmission_control_protocol

http://en.wikipedia.org/wiki/Operating_systems

http://en.wikipedia.org/wiki/Convergence


technology can also be useful for attracting visitors. The site must be attractive and

innovative in its design, function in terms of its purpose, easy to navigate, frequently

updated and fast to download. When users view a page, they can only view one page

at a time. As a result, multimedia users must create a “mental model of information

structure” [WIKI2008].

2.10 Database

A database is a collection of information organized in such a way that a

computer program can quickly select desired pieces of data. You can think of a

database as an electronic filing system. Traditional databases are organized by fields,

records and files. Comparatively, a field is a single piece of information while a

record is one complete set of fields. Lastly, a file is known as a collection of records

[WEBO2008].

2.10.1 Database Security

Database Security is a system, processes and procedures that protect a

database from unintended activity. Unintended activity can be categorized as

authenticated misuse, malicious attacks or inadvertent mistakes made by

authorized individuals or processes. Database security is also a specialty within

the broader discipline of computer security [WIKI2008].

The system will be provided by different levels of access. Therefore,

not all authorize users can access the same module in the system. Only the

manager or administrator will be given the authority to access all of the

modules in the system. This is one way of ensuring and protecting the system

from unauthorized users.

2.10.2 Database Normalization

Database Normalization, sometimes referred to as canonical synthesis,

is a technique for designing relational database tables to minimize duplication

of information and, in so doing, to safeguard the database against certain types

of logical or structural problems, namely data anomalies.

The Normal Forms (abbrev. NF) of relational database theory provides

criteria for determining a table's degree of vulnerability to logical

inconsistencies and anomalies. The higher the normal form applicable to a

table, the less vulnerable it is to inconsistencies and anomalies [WIKI2008].

First Normal Form (1NF) - a relation is said to be in First Normal

Form (1NF) if and only if each attribute of the relation is atomic. More simply,

to be in 1NF, each column must contain only a single value and each row must

contain the same columns.

Second Normal Form (2NF) - a relation must first fulfill the

requirements to be in first normal form. Additionally, each nonkey attribute in

the relation must be functionally dependent upon the primary key.

Third Normal Form (3NF) - a relation must first fulfill the

requirements to be in Second Normal Form. Additionally, all attributes that are

not dependent upon the primary key must be eliminated.

Boyce-Codd Normal Form (BCNF) - a relation is in Boyce Codd

Normal Form if and only if every determinant is a candidate key.

http://en.wikipedia.org/wiki/Relational_database

http://en.wikipedia.org/wiki/Table_%28database%29


Fourth Normal Form (4NF) - a relation must first be in Boyce-Codd

Normal Form. Additionally, a given relation may not contain more than one

multivalued dependency [ENCA2008].

Database normalization will be implemented to make sure none of the

data are redundant or duplicated. This will as well eliminate unnecessary

records found in the database. The uses of normal forms are of much help in

implementing this normalization process.

2.11 Electronic Commerce

Electronic Commerce or e-commerce is the exchange of goods and services

by means of the Internet or other computer networks. E-commerce follows the same

basic principles as traditional commerce that is, buyers and sellers come together to

exchange goods for money. But rather than conducting business in the traditional

way in stores and other “brick and mortar” buildings or through mail order catalogs

and telephone operators in e-commerce buyers and sellers transact business over

networked computers.

E-commerce offers buyers convenience. They can visit the World Wide

Web sites of multiple vendors twenty four (24) hours a day and seven days a week to

compare prices and make purchases without having to leave their homes or offices.

In some cases, consumers can immediately obtain a product or service, such as an

electronic book, a music file, or computer software by downloading it over the

Internet [ENCA2008].

2.12 Summary

This chapter discusses the theories that were used by the proponents in

developing the system for Pacla Hydraulic House.

Internet is a composed of many interconnected computer networks. Each

network may link tens, hundreds or even thousands of computers, enabling them to

share information and processing power. Internet platform will be used to provide and

exchange information about the system and the company to end-users. Through its

hypertext-based technology capability, it would be easier for the proponents to

display text, graphics, animations and navigation tools on-line regardless of the web

browser being uses. Web browsers allow users to quickly and easily access

information provided on many Web pages at many websites by traversing hyperlinks.

World Wide Web is a system of interlinked hypertext documents accessed

via the Internet. In order to display the different modules of the web application

which are formatted in an HTML, the proponents will make use of the World Wide

Web platform to do it so. Navigational links, either textual or graphical link, will be

provided so that users can jump from one module to another. Two of the most

commonly used web browsers that uses WWW technology are Mozilla Firefox and

Internet Explorer. Website is a collection of Web pages, images, videos or other

digital assets that is hosted on one or more web servers, usually accessible via the

Internet. Technically, the proposed system is a website for Pacla Hydraulic House. It

composes of different modules commonly known as web pages. These pages can be

accessed through the use of links which are provided to help users in jumping from

http://encarta.msn.com/encyclopedia_761567995/Network_(computer_science).html







one page to another page. Web page is a resource of information that is suitable for

the World Wide Web and can be accessed through a web browser.

A Graphical User Interface (GUI) is a display format that enables the user to

choose commands, start programs and see lists of files and other options by pointing

to pictorial representations (icons) and lists of menu items on the screen (User

Interface). Proponents will make use of point of contact interface between a computer

and its user. It means that graphical icons and visual indicators will be displayed as

oppose to text-based interface or character-based interface to fully represent the

information and actions available to a user. This graphic-based interface can be easily

manipulated and activated with the used of input devices such as mouse and

keyboard.

Wide Area Network (WAN) is a computer network that is meant to cover a

wide geographic area, usually over telephone lines, as compared to a local area

network that operates in a single company or institution. Because of its capability to

extend beyond the geographical limitation of a local area network, the proposed

system for Pacla Hydraulic House can be accessed by the potential customers

worldwide, wherever they are and whatever time it is. The use of internet, the worlds

largest WAN in existence, Pacla Hydraulic House can expand its marketing and

advertising strategies through global competitiveness. This gives them an opportunity

to increase its sales to the fast-growing internet-savvy crowd. Local Area Network is

a collection of interconnected computers that can share data, applications and

resources such as printers.

http://encarta.msn.com/encyclopedia_761572129/User_Interface.html




Hypertext Transfer Protocol is a communication protocol for the transfer of

information on the Internet. As the main communication protocol, the proponents will

use Hypertext Transfer Protocol in publishing the system over the internet and to

transfer information from the server and to retrieve those requested information then

be displayed on the end user with the use of a web browser. File Transfer Protocol is

a network protocol used to transfer data from one computer to another through a

network, such as the Internet. Since the proposed system involves request for

quotation, the proponents will use FTP to send the requested quotation to their clients.

A database is a collection of information organized in such a way that a

computer program can quickly select desired pieces of data. The proponents had

developed a database to have uniform repository of records and/or data. The

proponents make use of MySQL in creating the said database. Through the use of

MySQL commands, the proponents can easily manipulate records stored on the

database. Database security is a system, processes and procedures that protect a

database from unintended activity. Database Normalization is a technique for

designing relational database tables to minimize duplication of information and in so

doing, to safeguard the database against certain types of logical or structural

problems, namely data anomalies. Database normalization will be implemented to

make sure none of the data are redundant or duplicated. This will as well eliminate

unnecessary records found in the database. The uses of normal forms are of much

help in implementing this normalization process. Electronic Commerce is the

exchange of goods and services by means of the Internet or other computer networks.

The proposed system is design and develops to provide on-line information and

ordering for Pacla Hydraulic House. With this concept, electronic commerce concept

was applied on the development of the system. Through rapid growth of internet, the

amount of trade conducted electronically had grown extraordinarily.


Chapter 3 An On-line Information and Ordering System for Pacla Hydraulic House

3.1 Introduction

The proponents had conducted interviews, observations and surveys to Pacla

Hydraulic House. Through this, the proponents knew the specific problems that the

company experiences with the current manual system. This problems lead to the

proposal of On-line information and ordering system for Pacla Hydraulic House. In

order to provide solutions to the problems cited at statement of the problem, the

proponents had maximized the use of internet technology and library for both on-line

research and book reference.

With the use of the proposed system, Pacla Hydraulic House will expand its

marketing arm and increase its sales both locally and globally. The on-line

information and ordering system will make the transaction faster and more accurate

particularly in ordering process and reports generation. This will as well make the

work more organized and of less paper works.

3.2 System Design Specification

The 4th Generation Techniques (4GT) methodology was used by the

proponents as a guide in developing the proposed system and to start with. During

the first phase, the requirements gathered, the proponents used different methods in

data gathering such as observation and interview and survey. An observation and

interview were conducted on the side of the company to understand more the flow of

the current system being used and to identify the problems encountered by the

employees on their day-to-day transaction. To get the opinions of the others

especially to those of the customers, a survey was conducted as well. As a result, the


proponents were able to come up with various problems which were provided by

corresponding objectives. These problems and objectives lead to the second phase of

the methodology, the design strategy.

On design strategy, the second phase, the proponents had created Context

Flow Diagram (CFD), Data Flow Diagram (DFD), Entity Relationship Diagram

(ERD) and Hierarchical Input Process Output Chart (HIPO Chart) to show the flow

and process of the transactions in Pacla Hydraulic House and to illustrate how the

database is being normalized as well as the relationship of the table to each other

through the use of these graphical designs. These diagramming methods provided a

clearer view in designing the system. The proponents had considered the system’s

interface that would take advantage of the computer's graphics capabilities to make

the program easier to use and to make it easier for users to move from one module to

another module without learning complex command languages. On this phase, the

database, user interface and reports design are considered and finalized.

Implementation, the third phase where in the proponents had implemented the

technical specification of the proposed system using fourth generation languages.

This is where the proponents had executed the design plan of the previous phase and

interpreted it using HTML, PHP and JavaScript codes. The different modules that

comprise the system were accomplished using programming codes. On this phase, the

proponents had tested the modules individually before going to the next module.

Through this, functions and operations of modules were improved, including screen

layouts, business rules and process diagrams.

http://www.webopedia.com/TERM/G/computer.html

http://www.webopedia.com/TERM/G/graphics.html

http://www.webopedia.com/TERM/G/command_language.html


Lastly, the testing phase focuses more on testing the overall performance of

the proposed on-line system together with the host company to know if the system

meets the requirements in terms of input, process and output [WIKI2008]. During this

phase, the proponents take an external perspective from the users who have no

knowledge of the inner design of the code or logic of the system. The system testing

is first done with relatively small amounts of data. After the system had ran

successfully with it, the system is tested with a full volume of data. This is done to

detect system failures and inconsistencies between modules that are integrated

together so that defects may be uncovered and corrected.

In the back end module, the proponents had implemented levels of access to

restrict users from accessing the entire system and for security purposes as well Back

end composes of File Maintenance, Reports, Transaction, Inventory Management,

and Utilities. Selected users can only access specific module of the back end unlike

with the administrator who has the authority to access all modules of the system.

In the front end, the proponents designed and developed an on-line ordering

module, terms and conditions, frequently asked question, search module and forum

module.

Different multimedia software’s like Dreamweaver, Flash and Photoshop

were used in developing the proposed web application. Also, theories regarding

Active Server Pages, HTML, PHP, LAN, WAN and JavaScript were also applied in

implementing the on-line information and ordering system for Pacla Hydraulic

House.


The Hardware requirements for the host company are at least an operating

system- Windows 98, with at least 256 megabyte (MB) Hard disk of memory, 100

megabyte hard disk space for the internet connection, 256 kilo bytes per second was

needed to have a fast access on the website and a printer for printing purposes.

3.8 Summary

This chapter discusses how the proponents provided the solution to the

statement of the problem, different techniques used in gathering information and the

graphical design tools used in developing the system such as, 4th Generation

Techniques (4GT), Context Flow Diagram (CFD), Data Flow Diagram (DFD), Entity

Relationship Diagram (ERD) and Hierarchical Input Process Output Chart (HIPO

Chart). The proponents used this to guide to their system and discussed the

functionalities and detailed description of the different components of the system as

well as the software and hardware components that were used in the system.


Chapter 4 PERFORMANCE ANALYSIS

4.1 Introduction

The On-line Information and Ordering System for Pacla Hydraulic House is mainly

designed and developed to allow customers transact on-line and for the company to easily

manage the inventory of the products, reducing the time, effort and cost spent in every

business transaction. The web application comprises of two main modules, the front-end and

the back-end. These two modules have different outputs. The first module is the front-end

which contains different pages that contain various functionalities. On the other hand, the

back-end contains the file maintenance, different transactions, stock adjustment form and

generates different kinds of reports.

In performance analysis, data and information of the current system were gathered

and reviewed. The proponents had conducted survey and interviews on the employees and

customers of Pacla Hydraulic House about the on-line information and ordering system. The

objective of the analysis is to clearly understand the current system and identify the

shortcomings or errors of both current and proposed systems which must be enhanced and

modified.

After the survey, the proponents will be able to determine if the system has met its

targets as stated on the previous chapters of this documentation. At this stage, the proponents

would encounter minimal problems and receive suggestions from the users that will serve as

a basis in enhancing the system.

4.2 Experimental

In designing, developing and implementing the proposed system, the proponents

conducted experiments. In the front-end the proponents, used electronic commerce because


the system focuses on on-line transactions such as ordering and advertising of the products.

On the side, the back-end of the on-line system uses the PHP Hypertext Preprocessor (PHP)

and MySQL in developing the system. This is were all the transactions and maintaining of

files coded and produced in all necessary outputs that will be used in the system.

In the back-end of the system there were different modules that were used on

maintaining the information and data. The file maintenance consists of different modules

information relevant to the company are being maintained and updated by authorized users.

The next menu is transaction module where transactions done with the system are place such

as the purchase order, back order and the customer order transaction. Under of the transaction

is the reports module where all kinds of reports by the company are generated, including the

delivery report, purchase order report, order report, customer back order report and the back

order report. The system also has utilities menu. Under this menu are the backup module,

archive module, audit trail module, restore of the database and level of access contains the

administrator, sales representative, inventory clerk and cashier.

In the front-end of the website there are links that lead to other pages or contents of

the website. These main navigational links includes home page, product page, order on-line

page, on-line registration, shopping cart, company profile, and request for quotation and

contact us.

Written below are the list criteria and criterion related to the objectives of the

proponents in designing, developing and implementing the on-line information and ordering

system. These were based from the survey form that was given to the customers and

employees of Pacla Hydraulic House. The proponents used the Slovan’s formula to identify

the number of customers who will be part of the survey, That is:


n = N

1 + Ne2

Where:

n = sample size

N = total population

E = error of margin

n = 100

1 + 100(0.1)2

= 100

1 + 1

= 100

4.3 Results and Analysis

The system is capable of maintaining the data on the database given by the company

and information about the customer’s orders. An audit trail is included in backend so that

whoever are logs on in the system will be automatically traced as well as authorized users

who do any action or changes in the system.

The proponents conducted a testing of the system in order for the proponents to

identify the different errors and to maintain data. The current result showed some errors that

the proponents had checked. At this stage, all errors are corrected and all outputs are checked

to meet accuracy.

The proponents conducted a survey to know and identify the advantages and

disadvantages of the existing system of the Pacla Hydraulic House. The proponents gave an

idea on how to design the proposed system. In like manner the proponents used the Slovin

Formula to determine the sample size of the population.


To compute for the percentage and analyze the result of the survey that was

conducted, the proponents had used the formula presented as:

Percentage (%) = (sample size / population) * 100

4.4 Summary

The proposed on-line information and ordering system for Pacla Hydraulic House is

basically composed of two major modules, one for the backend and the other one is for the

front end. Both modules are accessible through on-line, however, the backend can only be

accessed by authorized users. In the backend module, there are four main menu which links

to other modules of the system. Similarly, the front end has also navigational links that leads

to other pages of the system.

After the survey, the proponents had identified the revisions needed on the system as

suggested by the host company. Based from the figures presented, the proponents had

satisfactorily achieved the objectives and purposes of the system in speeding up all business

related transactions, eliminating paper works and reducing cost spent in business processing.


Chapter 5 CONCLUSION

Pacla Hydraulic House does not have an existing website. It uses a manual system

in all of its transactions such as ordering inquiry and cancellation of orders, without

mentioning or naming a few. The host company introduces their products to potential

customers by presenting a book binder where the products are listed, and sometimes the

sales representative goes to their clients to introduce to them the products as well as the

new products. They monitor the orders and the product sold by using a piece of paper or a

log book. Also, the inventory clerk manually counts the incoming and outgoing products

daily. After counting the products, the representative will list down all the number of

products sold and returned in a piece of paper. The company uses logbook or any paper

of its form to record it. With the current system, the firm encounters problem in

marketing and advertisement, accuracy of reports and order details and in inventory.

The proponents aim to design, develop and implement a website that will provide

two (2) on-line product catalogues. Direct ordering and request for quotation was

provided to display the products as well as the information of the products. Through the

on-line ordering module, customers can place an order even outside the business firm.

The system automatically updates the availability of products as well as the incoming and

outgoing products of the company with the inventory management implemented by the

proponents in the system. This website will help the company to entertain customers in

far location and promote their products. These will be accomplished by making sure that

all the following requirements are met:

To design, develop and implement an on-line catalog that will display the

information of the products of Pacla Hydraulic House.


To design, develop and implement an on-line ordering module that will allow

their customers to place their orders.

To implement an inventory management that will easily monitor and update

products.

To design, develop and implement a search module that will efficiently locate

specific products.

To design, develop and implement a module that will generate faster, more

reliable and timely reports.

To design, develop and implement a security module that will secure the file and

prevent the access of the unauthorized personnel.

In order to meet all requirements, the proponents identified first the current

problems of the company and provided solutions based on the problems that were

encountered and accomplished all the scope of the system that was discussed on the first

chapter of the documentation.

Recommendations:

This system will provide on-line product catalog to be able for the customer to view

the list of products provided by the company.

This system will provide on-line ordering. This will be used by a customer to place

orders.

The proponents will provide a system which will easily monitor the availability of the

products as well as monitoring the products that are in critical level.

This system will provide a database to organize the important files made and

produced by the company.


This system will assist and guide the company to expand its market and sales.

The proponents will recommend the company to conduct training and seminar for

employees on how to use the system and to increase their knowledge in computer

based system.

The proponents will recommend using other software and hardware to upgrade the

system.
