ABSTRACT

With the advance of Internet, e-commerce has now grown to enormous

proportions, and On-line Banking and shopping have proven to be such a success that

the goal of business has become the provision of services that are available from

anywhere and that over half of Internet access will be through non-PC. The mobile

phone has become a part of daily life for many people, carry around everywhere with

them, all day long.

Over recent years, the trend toward smaller and faster devices, coupled with the

need for information access on the move, has paved the way for a new technology that

brings together the two worlds of the Web and the mobile phone. The Wireless

Application Protocol (WAP) is an industry-wide standard, defining a communications

protocol and application environment that allows us to access Internet content and

services from mobile phones. Designed from the ground up for low-power, small-screen

devices with limited input capabilities and low bandwidth, W AP has enabled the

development of a new breed of Internet-ready phones a mass-market price. It introduces

a new way of looking at the wireless phenomenon, letting the applications follow their

customers and provide them with innovative services.

The proposed system is developed to improve the web search book to access the

information of researches from anywhere by the mobile phone. It makes the web search

book and view l(brary record support mobility by W AP technology. Furthermore, it

provides accurate information of the search result. The proposed system is developed

using modem structured system analysis and design techniques.

I. INTRODUCTION

1.1 Background of the Project

Mobile phones are becoming popular in people's daily lives, and it has functioned

more than a simple communication device. The new technology of mobile phone enables

flexible access to information at online services such as online tickets, e-mail, and so on.

This has become possible due to the integration of mobile phone and lnternet

technologies or commonly called WAP technology. WAP, Wireless Application Protocol,

is the protocol that enables mobile phones and PDAs to connect to the Internet and

communicate with computer systems.

With this new development trend of mobile technology, one useful application is

adopted by library services, whereby searches for traditional written documents and

catalogues cards could be serviced through WAP. In this way, library services could be

opened for access 24 hours a day from anywhere, even without a computer connection.

Through the integration of wireless technology with that of the Internet,

productivity and efficiency could be derived. The usefulness of the Internet is therefore

extended to the mobile phone users.

1.2 Objectives of the Project

The objectives of developing the project are as follows:

(1) To provide library book search service by mobile phone in using WAP

technology.

(2) To save time on library services.

(3) To increase the efficiency of library work.

(4) To prepare a necessary platform for other services like borrowing and

returning books.

(5) To provide a new communication channel to users and give more service

alternatives to the users for maximum user' satisfaction.

1.3 Scope of the Project

The project covers major parts of the Mobile Library System which includes:

( 1) To search books at the library by mobile phone.

(2) To check current borrowed item by mobile phone users.

1.4 Deliverable

Three components of the system will be delivered. First is System Analysis, which

consists of Data Modeling Entity Relationship Diagram (ERO), Process Modeling

Functional Decomposition and Data Flow Diagram (DFD), and Network Modeling. The

second portion is System Design, which includes Feasibility Analysis, Physical Entity

Relationship Diagram, Physical Data Flow Diagram, Network Topology Diagram,

Interface and input/output design and System Structure. The Third portion is System

Implementation. The system will be operated in the real production environment of the

Central Library of Assumption University.

1.5 Project Plan (Including Gantt Chart)

The Mobile Library System started from the beginning of April till the end of June

2004. The project plan consists of three phases; system analysis phase, system design

phase and system implementation phase. See Figure 1.1 Project Plan.

(1) System Analysis Phase

System Analysis is the dissection of a system into its components to

study how those components interact and work. This phase surveys the plans

of the system and project first. Then the study analyzes of the existing

business and information system and the definition of business requirements

and priorities for a new or improved system. The models are structured

2

pictures that illustrate the processes, inputs, outputs, and files required

responding to business events. System and business analysts draw a series of

process models called Data Flow Diagram that depicts essential processes of

a system along with inputs, outputs, and files.

(2) System Design Phase

System Design 1s the evaluation of alternative solution and the

specification of a detailed computer-based solution. It is also called physical

design. Structure design technique that is used for design is modern

structured design. Modern structured design is a process-oriented technique

for breaking up a large program into an hierarchy of modules that result in a

computer program that is easier to implement and maintain. The software

model derived from structured design is called a Structure Chart. The

Structure Chart is derived by studying the flow of data through the program.

(3) System Implementation Phase

System Implementation is the construction of the new system and the

delivery of that system into production. Construction is to build and test a

functional system that fulfills business requirement and to implement the

interfaces between the new system and existing production system. System

Implementation consists of the construction and delivery phase. The

construction phase comprises of building and testing networks, building and

testing databases, installing and testing new software package, and writing

and testing new programs. Delivery phase comprises of conduction of system

test, preparation of conversion plan, installation of database, training system

and finally conversion to the new system.

II. THE EXISTING SYSTEM

2.1 Background of the Organization

ABAC, or Assumption University as it is now known, was originally initiated in

1969. It was formally established in June 1972 and accredited by the Ministry of

Education and the Ministry of University Affairs in May 1975. This University is

administered by the Montfort Brothers of St.Gabriel, a worldwide Catholic Religious

Order devoted to education and philanthropic activities. Assumption University has two

libraries. St. Gabriel's Library is located at Huamark Campus and Cathedral of Learning

is located at Bangna Campus. The organization chart of Central Library of Assumption

University is shown in Figure 2.1. Now the library uses new technology for developing

the library system by operating a website for searching books on the website, called

online catalogue. Users can search for books by various methods.

The Library System offers the following various methods:

( 1) Search or browse, by using exact key word.

(2) Search by Title, Author, Subject, Accession Number, ISBN, Series, and Call

Number.

(3) Type of Materials.

(4) Search by Location.

(5) Type word(s) in the box.

2.2 Problem in the Existing System

In fact, there are not so many problems in the existing system. The new

development for mobile research system aims for the following:

( 1) Convenient Service.

At present, users have to connect to the university library network

either by home linking or directly by using university computer facility to

search for a book. Although the current system functions well, more

convenient service is preferred by users. The mobile research system could

provide more convenient service to library users at anytime and anywhere

without using the computer.

(2) Alternative choice for book search

The new mobile research system provides a different platform for

library users in searching books. Nowadays, service quality is an important

factor to any organization. Users require good service. In order to provide

better service to satisfy the users' requirements, the library has to improve its

service by all means. A new search channel would give a new alternative

choice in searching of book by library users.

2.3 The Existing Business Function

In the existing system, main business functions are as follows:

( 1) Users can search for books on the website.

The existing system is able to provide the books available information

for users' checking. It also provides basic information of the book. The users

can easily find the book by searching the book information, and then look for

the book on the bookshelf

(2) Users can view current borrowed items on the website.

To save time in looking for a book, the existing system is able to

indicate the borrowed item information. It includes the due date. Users can

reserve the book in advance based on the due date of book.

III. THE PROPOSED SYSTEM

3.1 User Requirement

In developing the Mobile Library System. the most important information is used

to analyze and design it. The proposed system meets the user requirements that will assist

the system in gaining an achievement.

(1) The user can search for books on a mobile phone.

(2) The user can view current borrowed items on a mobile phone.

(3) Mobile Library System will provide more convenient service to library users.

3.2 The Proposed Business Data

After studying data modeling and process modeling of the existing system and user

requirement, a data modeling to depict the proposed system is created.

The figures of data modeling of the proposed system are shown below:

(1) Context Entity Relationship Diagram.

(2) Key-Based Entity Relationship Diagram.

(3) Fully Attributed Entity Relationship Diagram.

3.4.3 Feasibility Analysis

The proposed system is considered on feasibility analysis. The benefits or activities

that occur in developing the proposed system will be measured. There are four general

categories of feasibility tests which are as follows:

( 1) Operational feasibility: Determines whether a proposed system is desirable

within the existing managerial and organization framework.

(2) Technical feasibility: Determines whether a proposed system can be

implemented with the available hardware, software, and technical resources.

(3) Scheduled feasibility: Determines whether how reasonable the timetable of a

proposed system is.

( 4) Economic feasibility: Determines whether the benefits of a proposed system

outweigh the costs.

All three candidates, shown in Table 3 .1, which depend on Feasibility Study shown

in Table 3.2, are called feasibility analysis matrix. It determines which candidate solution

referred to the candidate systems matrix is feasible, or achievable, given the

organization's resources and constraints. There are four major areas of feasibility. They

must be addressed, as operational feasibility, technical feasibility, economic feasibility,

and schedule feasibility. The candidates will be given scores for each criterion. After

scoring, a final score is recorded in the last row for assessment. This matrix format can be

most useful in defending our management reputation.

After analyzing the feasibility analysis matrix of each candidate, the second

candidate is selected to propose to the managing director for approval so that the system

design will be initiated.

3.4.4 Hardware for the W AP Application Server

The proposed system will use Internet and W AP system, therefore the server must

have the hardware specification which can support the function of Web Application

Server. It should be stable and reliable for serving multiple users. The hardware

specification should be Intel Xeon 2.8 GHz used as W AP Application Server run on

Window 2000 Advance Server operating system and Internet Information Server 5.0 for

the Web Server. The details of hardware specifications for the W AP Application Server

are shown in Tables 3.3.

3.4.6 Software

Mobile Library System will be developed using WML to display the content to the

W AP browsers on mobile devices. The details of software specifications for the W AP

Application Server are shown in Table 3.5.

Table 3.5. Software Specification for WAP Application Server.


Microsoft Windows 2000 Advanced Server Operating System Internet Information Server WAP Server

In order to enable a web server to host W AP applications, we merely need to add

the MIME types for W AP files in the configuration setting of the server. MIME

(Multipurpose Internet Mail Extensions) is a method used to convert and transmit files

over the Internet. Most W AP browsers accept only W AP MIME types, and sending a file

with the wrong type in the header will generate an error.

On the part of database server, we develop database on the SQL server version

2000 and it runs on Windows 2000 Server. The details of software specifications for the

WAP Application Server is shown in Table 3.6.

Table 3.6. Software Specification for Database Server.

3.4.7 Network Configuration

W AP has three elements of network, which have different functions as follows:

(1) Content/Origin/ Application Server: This is the element in the network where

the information or web/W AP applications reside. (Web servers belong to this

category)

(2) Proxy: This is an intermediary element, acting both as a client and as a server

in the network. It is located between clients and original servers; the clients

send requests to it and it retrieves and catches the information needed by

contacting the original servers.

(3) Gateway: This is an intermediary element usually used to connect two

different types of network. It receives requests directly from the clients as if it

actually were the original server from where the clients want to retrieve the

information. The clients are usually unaware that they are speaking to the

gateway.

In this system, we choose the first element for the solution of network configuration.

To access an application stored on the server, the client initiates a connection with the

WAP gateway, and sends a request for content. The gateway converts the request coming

from the W AP client into the format used over the Internet (HTTP), and then forwards it

to the original server. On the way back, the content is sent from the server to the gateway,

which then translates it to W AP format, and then sends it to the mobile device. The

gateway allows the Internet to talk to the wireless network. As with the database server

solution, business logics could be distributed to the W AP application server. The network

configuration is shown in Figure 3.12.

3.5 Security and Control

The basic concepts of security are as follows:

( 1) Authentication

(2) Confidentiality

(3) Integrity

( 4) Authorization

(5) Non-repudiation

Authentication is the process of making sure that another party is actually who they

claim to be. There are many different ways of authenticating parties to a transaction

organization. The participants in the transaction need to agree an authentication protocol

that they are capable of using and that meets their requirements. Confidentiality is one of

the most important aspects of security. While authentication may have conclusively

identified the participants in a transaction, the information that the two parties are

communicating will be sensitive or intercepted. It is necessary to assume that

communications will be intercepted and take steps to ensure that when the information is

intercepted it cannot be understood or used. It is usually encrypted.

Integrity assumes that messages can be interfered with along the way. We need to

be able to make sure that the message was not tampered with during transmission.

Authorization is the process of determining whether a particular party has the right to

perform a particular action with respect to a particular object, in a particular situation. For

authorization to be meaningful there has to be, at the very least, an effective mechanism

of authentication. Authentication is, therefore, a necessary prerequisite for authorization.

Non-repudiation means implementing some sort of mechanism so that it is impossible for

the parties to a transaction to deny either that the transaction took place, or that they were

party to it.

35

Achieving security of database environment means identifying the threats and

choosing the proper policies (what the security system is expected to do) and mechanisms

(how the security system should achieve the security goals). Therefore, Information

Security Policies and Standard have been established in order to lay down corporate-wide

guideline for the protection of information asset. These are described in the following

sections.

3.5.1 Data Security

(I) Provisions are made for the recovery and restoration of information lost due

to computer failure, loss, and disaster or operator's error.

(2) Back-up copies of processing data/software must be made at least daily. The

W AP application server includes the tape backup device for backing up the

system and data. Other micro-based information must be backed up on a

schedule that reasonably reflects the risk associated with losing it.

3.5.2 Physical Security

(1) Uninterruptible Power Supply (UPS): UPS system will supply power to the

system controller (WAP application server and database server) to continue

some processing job for a short period of time after the outage of the main

power.

(2) Hot Plug Redundant Power Supply: When the main power supply is damaged,

we can swap the new power supply to the system immediately without having

to down the system.

IV. PROJECTIMPLEMENTATION

4.1 Overview of Project Implementation

The proposed system will be implemented after we pass through system analysis

and system design phase. In each phase where considerable work and time are

represented, the phases are usually broken down into activities and tasks that can be more

easily managed and accomplished. To develop the Mobile Library System it takes four

months. It starts from the beginning of April till the end of June 2004.

System implementation is the planned and orderly conversion from a current

existing system to the new proposed information system. The proposed system should

meet the desired objectives. System Implementation consists of Construction and

Delivery Phases.

Construction Phase

The construction phase is actually part of design/construction loop. The purposes

of the construction are to build and test a functional system that fulfills the business

requirements and to implement the interfaces between the new system and the existing

production system. To implement the proposed system, we set up two new servers. First

is the Wireless Application Protocol application server and the other is SQL database

server. For the Wireless Application Protocol application server, it is the Intel Xeon 2.8

GHz, 512 MB memory, and 36.4 GB hard drive. Windows 2000 advanced server is

installed with service pack 2 for an operating system. Later we set up the Internet

Information Server 5.0 (ISS 5.0), which is provided as standard web server with

Windows 2000 advanced server to know about MIME types of Wireless Application

Protocol standard. After that we need to configure demo Wireless Application Protocol

Site on Internet Information Server to test the proposed system. In addition, Mobile

40

Library System program is installed in the virtual directory of Wireless Application

Protocol Site that we set. Third, we setup the database server with Window 2000

advanced server operating system and install SQL server 2000. Then, we create database

for testing on SQL Server.

Delivery Phase

Delivery Phase means delivering the new system into operation. We can test the

proposed system via the W AP browser on mobile devices or the W AP emulator such as

Nokia Wireless Application Protocol Toolkit, UP.simulator, WapIDE of Ericsson, etc.

Then a manual document is made for training users.

4.2 Test Plan

Testing is an important skill that includes Unit testing, System testing and

Regression testing.

(1) Unit or program testing is a test whereby all the modules have been coded

and stub tested as an integrated unit. The test data and current performance

that are benchmarked are used here.

(2) System testing ensures that the entire application, of which the modified

program was a part, still works. Again, the test data and current performance

are used here.

(3) Regression testing extrapolates the impact of the changes on program and

application throughput and response time from the before and after results

using the test data and current performance.

4.3 Training

Training is provided for both system administrator and functionary in IT

department. System administrator and functionary have to operate the system in their

41

daily work. So training of proper use of the system will reduce errors in data entering and

reduce time in searching data.

42

V. CONCLUSIONS AND RECOMMENDATIONS

5.1 Conclusions

The project study concerns the Mobile Library System for a well established

concrete organization, Central Library of Assumption University. The area under study

describes the use of Wireless Application Protocol architecture to handle and improve the

efficiency in searching book and viewing library record.

The Mobile Library System is conducted to improve the activity of Central Library

of Assumption University and to ease the process for users who want to search book and

view library record. They can use the system anywhere, anytime by their mobile phones.

In depth analysis, design and implementation are on Central Library of Assumption

University according to Central Library of Assumption University's requirement. The

reason why the Mobile Library System is so important is the need for improving

efficiency and reducing process time.

This proposed system is designed and implemented in a way to solve the existing

problems and result in satisfying the user requirement and improving the management of

Central Library of Assumption University. Mobile Library System will be a base system

that brings the development trend of mobile user; one useful application to library

services. Through the integration of wireless technology with that of the Internet,

productivity and efficiency could be derived. The usefulness of the Internet is therefore

extended to the mobile phone users.

The proposed system operates in less time than the existing system that needs many

unnecessary steps. Table 5.1 shows the time performance on each process of the

proposed system compared to the existing system.

5.2 Recommendations

Normally, whenever starting a WAP session on the mobile phone, the following

steps are executed.

( 1) A connection is created via WSP (Wireless Session Protocol) between the

mobile device and the WAP gateway.

(2) On entering the address of W AP site (By typing it or by selecting a bookmark)

the gateway sends a request from the device's micro browser using WSP.

WSP is the W AP protocol in charge of starting and ending the connections

from the mobile devices to the WAP gateway.

(3) The gateway translates the WSP request into an HTTP request and sends it to

the appropriate original server.

(4) The original server sends back the requested information to the gateway via

HTTP.

(5) The gateway translates and compresses the information and sends it back to

micro browser in the mobile phone.

( 6) The gateway takes care of translating all the requests that are sent and

received by client using WSP to the protocol.

(7) The W AP gateway is presented in the operator network such as Advance Info

Service that provides the interface for accessing some of the network service

the operator wants to provide. Nevertheless, the companies can have their

44

own gateway, especially Internet network that is the best solution to install

their own gateway.

Security Control Section

WTLS (Wireless Transport Layer Security) is the solution to security, which in turn

1s based on SSL. SSL delivers methods to encrypt the data content and to make it

accessible only to entrusted users. Furthermore, it gives the users the ability to check

whether the content they are requesting really comes from the original server it is

supposed to. WTLS provides the same grade of security that is supplied by SSL. It

provides services that ensure privacy, server authentication, client authentication, and

data integrity.

(1) Privacy guarantees that the data sent between the server and the client is not

accessible to anyone else. No one can read the encrypted message, although

they can see the encrypted message.

(2) Server authentication ensures that the server really is who it claims to be, and

that it is not an imposter.

(3) Client authentication provides a way for the original server to limit access to

the content it provides. Just those subscribers that are recognized as trusted

ones can gain access to the site.

(4) Data integrity takes care that no one can alter the content as message begins

transmitting between server and client without one of them noticing.

In the diagram that follows, we show how the W AP gateway handles secure

sessions. A standard SSL session is opened between the web server and the W AP

gateway and a WTLS session is initialized between the gateway and the mobile device.

The encrypted content is sent it to the mobile phone. Figure 5.1 shows secure sessions on

WAP gateway.
