Book Shop Management

The National Degree College Basavanagudi Page 1

PROJECT OVERVIEW

Problem Definition:

The main aim of the project entitled “BOOK SHOP MANAGEMENT” is to provide an

application for the book shop.

This project is developed with four layers, which are:

1. Security

2. Employee Details

3. Book Details

4. Maintenance of Sales and Purchase

Problem Description:

1. Security: in manual book keeping all the entries are basically done through entry in

the books, where chances of manipulation are more but in this project the records

maintained are more secure as an outsider cannot manipulate the database without

knowing the password.

2. Employee Details: This project provides a provision for maintaining the employee

database apart from the maintenance of Book Database.

3. Book Details: The information regarding books i.e., book name, author, publication

etc., are provided for the customers for their convenience. As this process is

computerized it is easy for the owner to update the list where this process would have

been difficult if he had maintained the records manually.

4. Maintenance of Sales and Purchase: All the Sales and purchases made by the owner

can be recorded in the separate database provided by this tool, which would be helpful

for him in the future for the development of his establishment.

VISUAL BASIC

Introduction:

Visual basic 6.0(VB 6.0) is the recent addition to the family of Microsoft Visual

Studio. VB 6.0 is specifically designed to utilize the internet. User can easily create Web-

based application called ActiveX executables, which are similar to Internet Explorer 4.0

or higher Web Browsers. VB 6.0 supports ADO (Active X Data Objects), DHTML & IIS

(Internet Information Services), and ISAPI‟s (Internet Server API). The formatting, string,

numeric functions and new validates events for input controls increase learning rate of a

novice programmer Today, VB 6.0 has become technology leader, implementing original

ways of doing things before any other visual programming development tools.

History of Visual Basic:

Earlier versions of VB (1.0&2.0) were considered as “Hobbyist„s language” had limited

features & dismal performance compared to applications written in other language like C.

VB 3.0 became much more database friendly and MS Jet engine was introduced along with

MS Access Databases.

VB 4.0 supported 32-bit programs; OCX or ActiveX & DDL were introduced along with

more powerful Jet engine.

VB5.0 was the first version of VB, which provides a native code compiler. i.e. generates

Machine code. It also supports ActiveX Documents, ActiveX DLL‟s

Power of VB 6.0:-

VB is an Event-driven programming language, in which the user will have full

control over the execution of the program i.e. the user can click a desired button or

any other control tool to invokes an event, which instantly executes the code

within that event procedure by the computer.

VB is by far the most popular Visual programming tool in existence.

Microsoft estimates they there are more than 3,000,000 VB programmers.



VB was the first programming language, which pr0vides Drag-and-drop interface

design to the general programmer.

VB PROVIDES Intelligence (The Visual Basic Text editor uses Intelligence to

make writing your code easier and more error-free. IntelliSense options

Include Statement Completion, which provides quick access to valid member

function or variables, including global, via the Members list. Selecting from the

list inserts the member into your code) Integrated Development Environment.

VB is unexcelled for RAP (Rapid Application Development) through its new Data

Environment and Data Report facilities specially meant for hierarchical database

organization & new wizards like Package and Development wizard and

Deployment wizard and Data Object generators wizards enables the users to easily

create setup programs and archives for the distribution of VB applications&

components & middle tier objects that are bound to User Controls & Data

Environments.

Visual Basic is not a case sensitive language & if the variables are not

System requirements for Visual Basic 6.0 Programming:-

Windows 95/NT4.0 or higher environment 32MB+ RAM 1 GB hard disk or capacity Color monitor (preferably) CD-ROM drive (Visual studio is available only on CD-ROM ) Mouse or any other Pointing Device

Creating Control arrays:

A control array is a group of controls that share the same name, type and same event

procedure. A control array should satisfy the following properties:

Contains at least one element and grow to as many elements as required by the

application.

It may contain up to 32767 elements.

Each control has a unique index.



There are three ways to create a control array at design time:

1. Assign the same name to more than one control.

2. Copy an existing control and then paste it onto the form.

3. Set the control‟s index property to a value that is not Null.

Data Access Objects (DAO):

Data Access Object was the first object-oriented interface that exposed the Microsoft Jet

database engine and allowed Visual Basic developers to directly connect to access tables as

well as other databases through ODBC. DAO is suited for either single-system application or

for small, local deployments

The General Characteristics of DAO are:

1. Difficulty in coding

2. Flexibility, with facilities to access many different Data sources.

3. Adequate-to-slow performance.

4. Dynamic Data Language (DDl) functionality.

5. Support for complex cursors

To create a new data report:

To create a new data report with the data report designer, a simple project that was created

earlier with the Data Environment designer will be used here. If the data report is not created

earlier, select project menu, click Add Data Report and visual basic will add the data

report to the project explorer window and display on the screen .If the designer is not on

the project menu, click Components, click the designer tab and then click Data Report to

add the designer to the menu.

On the properties window, click Data Source and then click Data Envirnoment1.then click

Student Table. Right –click the Data Report designer, a shortcut menu appear on the screen

and then click Retrieve Structure to retrieve all the field structures of the command object

student table to Header and other sections. The Data Report designer added a new group

section to the designer .Each group section has a one-to-one correspondence to a command

object in the data environment; in case the new group section corresponds to the student

table command object.



MICROSOFT ACCESS

Databases are store –houses of information. For retrieving any information, we fall back on

databases. Herein comes the role of database management system which helps in systematic

organization of information. Amongst the many database management systems available in

the market, Access is quite useful and popular because of its unique features.

A database has many advantages. Many of the useful databases are those which can provide

latest information. The information in a database should be organized in such a way that it is

easy to update. And only then, it can quickly provide the information.

Any stored information or a database, whether electronic or manual, helps you by keeping

track of your inventories, payroll, invoicing or anything else that you consider important.

Defining a Database

A database is an organized collection of related information about a particular subject or

purpose; for example, information regarding the price of a book or the profile of an

individual in any organization. Consider, for instance, the example of a box full of index

cards carrying the names and prices of the books of a particular author.

In computers, a database is like a box containing index cards. The only is the difference is

that instead of index cards, a computer database is filled with records. While each index

card in the box contains information written in many lines, a record in a database contains all

the information related to an item in just one line. Information in a database is stores in rows

(records) and columns (fields), as shown below:

Column 1 Column 2 Column 3 Column 4

Field 1

BOOK NAME

Field 2

BOOK CODE

Field 3

AUTHOR

Field 4

PRICE

C PROGRAMMING 4521 P.B. KOTUR 150

VISUAL BASIC 4522 DIETAL & DIETAL 450

Table



The names given to each column, i.e. BOOK NAME, BOOK CODE, AUTHOR and PRICE

are called field names. In the given database, the first record contains the information about

the book C-PROGRAMMING. The second record contains information about the book

VISUAL BASIC. In the above example, we have shown only two records. But in computers,

a database can contain large amount of information. Such type of database is called an

electronic database.

Thus, an electronic database is a collection of logically related information that you store in

your computer. It also acts like an assistant to you who is always ready to store, organize and

extract information.

RDBMS

A Relational Database Management system is defined as a method of viewing information

from several, separate databases that relate to one another through keywords or values. The

main advantage of a relational database management system is that you can simultaneously

use more than one database to see information stored in them.

Another advantage of relational database design is that you can extract fields from different

databases and see them on the screen at one time thus reducing the complexity.

Objects of a Relational Database

Microsoft Access is based on RDBMS. Therefore, to have better understandings of working

in Access, you should be familiar with four basic objects of RDBMS as described below:

RDBMS

Tables Queries Forms Reports

Tables

A Table is a collection of information on a specific topic. In a table, the information is stored

in rows and columns. You can store different types of data in different tables.



Queries

Queries are a systematic way of retrieving information from a database.

Forms

Forms present the information stores in a database in an easy to use format. Through Forms,

you can view, enter or update information in a database, Forms present one record at a time

on the screen. But if you wish to enter or update information in your database.

Reports

Let us assume that you are in charge of maintaining the list food items in your company and

your boss has asked you to produce a report of the items which have a demand in the market.

In such a case, you can use the Reports feature to design the requires report in such a way

that it becomes easy for your boss to quickly understand all its details.

Functions of a Database Management System (DBMS)

A database management system is a tool for managing information, stored in the database.

Managing a database includes the following functions:

Creating a Database

Modifying a Database

Adding Records in a Database

Deleting a Records in a Database

Selecting Records in a Database



Brief History of SQL

SQL or Structured Query Language is the language used to talk to Relational Databases. The

Relational Database model for database design was invented by Dr.E.F. Cobb in 1969 and

published in Computer World in 1985.SQL was first implemented in 1974 at IBM the San

Jose Research Laboratory. SQL is essentially a non-procedural language that uses English-

like words to talk to a database. The American National Standards Institute (ANSI) is

continually updating their versions of SQL standards.



SOFTWARE ENGINEERING

Software Engineering is a systematic approach to the development, operation, maintenance

and requirement of software. The basic goal of the software engineering is to provide high

quality software at low cost. The basic activity or phrases to be performed for developing a

software system are:

Requirement Analysis:

In this phase, the software engineers carry out a detailed study of user‟s requirements. The

emphasis in requirement analysis is on identifying what is needed from the system and how

the system will achieve the goal.

There are two main activities in this phase:

1. Problem Analysis: Here the analyst has to understand problem and its content.

2. Requirement Specification: It focuses on clearly specifying the requirement in a

document issues such as

Representation

Specification languages and

Tools

In most software projects, the requirement phase ends with a document describing all

requirements, which is called as Software Requirement Specification (SRS) document.

Software Design:

The purpose of the design phase is to specify the particular software system that will meet

the stated requirements. The design of a system is perhaps the most critical factor affecting

the quality of the software and has a major impact on later phase.

The design specifications that get generated at the end of this phase are technical in nature

and contain:



1. User Interfaces

2. Databases and Data structures

3. Algorithms

The design activity is divided into two phases:

1. System Design: It is also called as top level design. It aims to identify the modules

that should be in the system, the specification of this module, and how they interact

with each other to produce the desired results

2. Detailed Design: During this phase, internal logic of each of the modules specified in

System Design is decided and further details of data structure and algorithmic design

of each of the modules is specified

Coding:

The goal of this phase is to translate design of the system into code in a give programming

language. The coding phase affects both testing and maintenance phase. If design is

performed in a detailed manner coding can be accomplished easily. Hence during this phase

the focus should be on developing the programs that are easy to write. Simplicity and Clarity

should be tried to follow during this phase.

Coding Style:

In a bottom-up approach the individual base elements of the system are first specified in

great detail. These elements are then linked together to form larger subsystem, which then in

turn are linked, sometimes in many levels, until a complete top-level system is formed. This

strategy often resembles a “seed” model, whereby the beginnings are small, but eventually

grow in complexity and completeness.

Object Oriented Programming (OOP) is a programming parading that uses “objects“ to

design application and computer programs.

In Mechanical Engineering with software program such as Pro/ENGINEER, Solid works,

and Autodesk Inventor users can design products as pieces not part of the whole and later

add those pieces together to form assemblies like building LEGO. Engineers call this piece

part design.



This bottom-up approach has one weakness. We need to use a lot of intuition to decide the

functionality that is to be provided by the module. If a system is to be built from existing

system, this approach is more suitable as it starts from some existing modules.

A bottom-up approach is the piecing together of systems to give rise to grander systems,

thus making the original systems sub-systems of the emergent system. In a bottom-up

approach the individual base elements of the system are first specified in great detail. These

elements are then linked together to form larger subsystems, which then in turn are linked,

sometimes in many levels, until a complete top-level system is formed. This strategy often

resembles a "seed" model, whereby the beginnings are small but eventually grow in

complexity and completeness. However, "organic strategies" may result in a tangle of

elements and subsystems, developed in isolation and subject to local optimization as opposed

to meeting a global purpose.

Testing:

Testing plays a very critical role for quality assurance and for insuring the reliability of

software. During testing the program to be tested is executed with a set of Test Cases and

output of the program for the test cases is evaluated to determine if the program is

performing as it is expected to.

There are four major types of testing:

1. Unit Testing: Here each module is tested separately. The coders himself often

perform this simultaneously along with coding of the module.

2. Integration Testing: Here many tested module are combined into subsystems, which

are then tested. The goal here is to see if the module can be integrated properly, the

emphasis being on testing interfaces between modules.

3. System Testing: Here the system is tested against the system requirements to see if

all the requirements are met and if the system performs as per the requirements

specified.

Maintenance:

Maintenance is a process of repairing and upgrading the system when required, to ensure

correct working of the system at all times. Any changes for the system required are intimated

to the analyst by the user. The analyst prepares an incremental model accessing the input of

modification. The management decides whether or not to implement the change. If the

change is approved, the analyst modifies the system documentation to reflect the changes.

Programmers help to modify and test the programs.

Maintenance is required when:

User requests change in the system

Programmers modify the programs

Testing team test the modified programs

Analyst modifies all system modification to reflect change
