1. INTRODUCTION

This project entitled “OWEN TRUST LIBRARY MANAGEMENT SYSTEM” is

developed for Owen Library. The main aim of the project is to transfer the manual

details into a full-fledged computerized. There are number of modules in this project.

They are Master Module, Transaction Module, Fine Modules and Search Module

The main aim of this project is to reduce the manual work in Library

processing. The system can easily maintain all Book Transaction, Amount, and

Status and also maintain the entire books in library, details of books and unit.

Through this project the time is saving and also the workload of the people working

in the organization is reduced, much.

The details of Library process have been computerized. The next important

feature is its user friendliness and easy navigation. Flexibility of the system is also

maintained. This is a client server programming, user can easily maintain all Library

process.

This project is implemented in VB.NET as frontend and with MS Access as

backend.

reducing the time in a cost effective manner. Also the workload of the people

working in the organization is reduced, much.



2. SYSTEM ANALYSIS

System Analysis is the process of gathering and interpreting facts, diagnosing

problems, and using the information to recommend improvements to the systems.

Analysis specifies what the system should do.

The first stage of software development is the study of the system under

consideration and its requirement analysis. During these stages constant interaction

with the users of the system is necessary. System analysis is the key to the life cycle.

To ensure the success of the system, careful and extensive analysis is required.

Analysis is a detailed study of various operations performed by the system. This

involves gathering information and using structured tools for analysis.

Objectives Of System Analysis:

Identify the customer’s need.

Evaluate the system concept for feasibility.

Perform economic and technical analysis.

Allocate function to hardware, software, people, database and

Other System elements.

Establish cost and schedule constraints.

Create a system definition that forms the foundation for all

Project and System scope


A repository is a collection of those places where we keep all documentation

associated with the application and project.

The purpose of the survey phase is to determine the worthiness of the

project and to create a plan to complete those projects deemed worthy. To

accomplish the survey phase objectives the system analyst will work to

1.Survey problems, opportunities and solutions.

2.Negotiate the project scope.

3.Plan the project

4.Present the project

The purpose of the study phase is to answer the questions. Are the problems

really worth solving? And is a new system really worth building? To answer these

questions, the study phase thoroughly analyzes the alleged problems and

opportunities first identified in the survey phase. The system analyst will

1.Optionally, model the current system.

2.Optionally analyze business processes.

3.Analyze problems and opportunities.

4.Establish system improvement objectives and Constraints.

5. Modify project scope and the problem.

6.Present the findings and recommendations.

The purpose of the definition phase is to identify what the new system is to do

without the consideration of technology; in other words, to define the business

requirements for a new system.



The analysis will

1.Outline business requirements.

2.Model the business system requirements.

3.Optionally build discovery prototypes.

4.Prioritize the business system requirements.

5.Modify the project plan and scope.

Approach

Determining the user requirement is not easy. System requirement change, the

articulation of requirements is difficult and heavy user involvement and

motivations are uncertain. Problems with the user analyst interface add further

difficulties to the procedure.

There are three strategies for eliciting information regarding the users

requirements asking question, obtaining information from the present system and

prototyping .The asking strategy assumes a stable system where the user is well

informed about information requirements. In contrast, prototyping strategy is

appropriate for high uncertainty information requirement determination



2.1 Existing system:

The existing system is done manually with lot of works imposed on the

people. And their having no formal way of Book Issuing, Book Returning, Bill

making and storing books and details about the library, and they are maintaining all

the information put only in paper work. Suppose we need particular information, this

is very difficult to take from the file. They have to maintain all works properly. The

existing system is difficult to maintain. So there are a lot of disadvantages in the

existing system.

Disadvantages of existing system:

1.Difficult to find out currently available books.

2. No proper maintain of our assets.

3. Few confuse arise while on booking.

4. No systematic relationship between borrower and management.

5. Paper valuation is a tedious process as each and every one of the papers is

to be corrected manually.

6. There may be many mistakes while correcting the papers and calculating

the accounts.

7. It takes a lot of time to prepare daily report.

8. There occurs a chance of missing the papers and files.

9. It takes lot of time to reach the books to customer.

10. Stock maintaining is difficult.



2.2 Proposed System:

The proposed system is a computerized one. The details about the Library

Management Processing are kept in the server of the system. All the manual works

are computerized. We see the account from any place at any time. It generates

automatic Id number and maintains all Books immediately. It gives sufficient

information when we are asking. We can monitor all stock details every minute and

also we can see the book details, Status of the books, Type of the books available etc.

Advantages of proposed system:

1. Generate all Id number automatically.

2. All the manual work is reduced, as there is no need of staff members.

3. No chance of errors in the system

4. Measuring and calculation of the damage are accurate.

5. Results can be displayed immediately so that the user need not wait for

their results to be displayed.

6. Processing of work is very fast and the time is reduced much.

7. Store all the appropriate information to corresponding files

8. It gives sufficient information when we are asking

About Sofware

.Net Framework

The .Net Framework is essentially a combination of the common language

runtime (CLR) and the standard classes that are available to .NET programmers. The

CLR is the execution environment for all programs in the .NET framework. It’s

similar in nature to the java virtual machine (JVM). The runtime classes provide

hundreds of prewritten services that clients can use as the basic building blocks for

an application.

Features of Common Language RunTime (CLR)

Consistent Programming Model

All application services are offered through a common object (OOPS).

Simplified Programming Model

There in no API(Application Programming Interface).

DLL Problems

.Net architecture removes the common problems caused by DLL versions.

Platforms

.Net application consists of managed code that can execute on any platform

that supports the .Net CLR.

Reuse of code/Language integration

.Net allows languages to be integrated with one another.



It is possible to create a class in C++ that derives from a class first

implemented in VB.

Types

.Net CLR verifies that all code is type safe.

Error Handling

All errors are reported as exceptions, which simplifies code maintain.

Compare to VB

VB 6.0, a programming language from Microsoft, is a popular language

because of the simplicity it offers in terms of syntax. However, it lacks the object

oriented programming approach. To overcome this drawback Microsoft in its

new .NET strategy revamped the existing VB to VB.NET.

Moreover, the VB.NET has following addition features compare to VB 6.0.

Object Oriented Programming

VB.NET allows developers to make use of object oriented features such as

classes, interfaces, inheritance and polymorphism. The main advantage of this is

code reuse. Code need no be built every time from scratch, but instead can be built

upon existing components thus saving time and effort for the developer.

Structured Error Handling

Errors are bound to occur in a program no matter how careful the developer

is during program development. Errors can be handled in VB.NET in a more

systematic and structured manner through the use of exceptions.

Multithreading



In a multithreading environment, each process is broken into one or more

threads. These threads when executed by the processor can sometimes cause

problems. This especially when multiple threads try to access shared data.

For example, a simple code like x=x+1 may fail if multiple threads attempt to

execute if simultaneously and x happens to be a shared variable among the threads.

This can be avoided if only the programmer manages the threads through the

program. VB.NET allows programmers to synchronize threads from within a

program which ultimately improves the performance of the program.

VB.Net Capabilities

VB.NET offers capabilities for developing the following.

Console Based Application (Notepad)

Web Application

Windows Application (GUI)

Windows Based Application (GUI)

Every windows based application has two parts

User Interface

Program

User Interface



A user interface is the screen through which the user interacts with the

application. Thus for any application to be successful it needs to have a good user

interface.

Program A program is a set of instructions that are used to carry out a specific task.

Console applications a created using VB.NET consists mainly of programs and no

user interface.

Class Library

Everything in the .NET framework is a class or an instance of a class. One of

the main components of the .NET framework is the Class library. Class libraries are

a collection of reusable classes or types. Some of the classes are form class, textbox

class, button class, label class, listbox class, combobox lass and checkbox class.

Form

A form is added automatically to the application when a new application is

created. When a form is added to the application, winforms created an instance of the

form class.

Controls are visual interface components that are placed on a form to create a

user interface. All controls that appear on a windows form inherit from the

usercontrol class.

Label



The label control contains descriptive text that is set and retrieved using the

control’s text property. It is used for designating names to the various controls on the

form.

Textbox

The Textbox control is used to get input from the user or display text to the

user. Some of the important properties of textbox are following.

Text - used to show and get the text that entered in textbox

MaxLength - used to set the maximum length in textbox

Password - used to act the textbox as password field (*****)

Button

The button control is the easiest way to allow the user to interact with an

application. The user can click the button to perform the required action.

ListBox

The ListBox control is used to display long lists of options from which the

user can choose. Each property in the list is called an item. There are two types of list

boxes supported in winforms.

Listbox

Checked Listbox



The difference between the listbox and the checkedlistbox is that in

checkedlistbox each list item is accompanied by a checkbox.

GetItemCheckState is an important method in checkedlistbox.

GetItemCheckState(integer)

Get particular item check state. If it is checked then it returns true otherwise

false.

Item

Item is used to retrieve the text of the particular item by using index value.

Example

Dim i

For i = 0 To CheckedListBox1.Items.Count - 1

If CheckedListBox1.GetItemCheckState(i) Then

msgbox(CheckedListBox1.Items.Item(i).ToString)

End If

Next

The above example views the item that is checked state in the checkedlistbox.

Combobox

The combobox control features of the Textbox and Listbox controls. This

control allows the user to select an item either by typing text into the combobox, or

by selecting it from the list.

By using add method we can add the items in combobox. Example



ComboBox1.Items.Add("car")

ComboBox1.Items.Add("bus")

ComboBox1.Items.Add("train")

Timer

The timer control is a component that raises an event at regular intervals. It is

like a clock that keeps on ticking at specified intervals and it raises an event.

Interval is a property represents the time period, in milliseconds between

each timer ticks.

Start and Stop methods are used to start and stop the timer tick event

respectively.

Tick is an event that triggered when the specified timer interval has elapsed

and the timer is enabled.

Scrollbars

There are two types of Scrollbars supported in winforms. They

HscrollBar

VscrollBar

Hscrollbar indicates the Horizontal scrollbar and Vscrollbar indicates the

Vertical Hscrollbar.



ProgressBar

The progress bar control is used to indicate the progress of an action. It

displays an appropriate number of rectangles arranged in a horizontal bar. When the

action is complete the bar gets filled.

ToolTip

The ToolTip control is used to display text when the mouse moves over a

particular control. For example, the ToolTip control can be used to display the

function of a button when the mouse is on that button.

About Access

Microsoft Access:

Using Microsoft access, we can manage all the information from a single

database file. Within the file, the data is divided into separate storage containers

called tables.

Tables

A table is a collection of data about specific topic such as registration etc.

using a separate table for each means; you can store the data only once, which makes

the database more efficient. A common field relates two tables so that Ms Access can

bring together the data from the table for viewing, editing or printing.

Queries



Queries are used to view, change & analyze data on different ways. It can be

used as the source of records for forms, reports and data access pages. An SQL query

is a query you create by using an SQL Statement. We can use Structured Query

Language (SQL) to query, update, and manage relational databases such as

Microsoft Access.

When we create a query in query design view, Access constructs the equivalent SQL

statements behind the scenes for you. In fact, most query properties in the property

sheet in query Design view have equivalent clauses and options available in SQL

view. If we want, to view or edit the SQL statements in SQL view. However, after

we make changes to a query in SQL view, the query might not be displayed the way

it was previously in Design view.

Some SQL queries, called SQL specific queries, can't be created in the design grid.

For pass through, data definition, and union queries, we must create the SQL

statements directly in SQL view. For sub queries, you enter the SQL in the Field row

or the Criteria row of the query design grid.

Forms:

A form is a type of a database object that is primarily used to enter or display

data in a database. You can also use a form as a switchboard that opens other forms

and reports in the database, or as a custom dialog box that accepts user input and

carries out an action based on the input. Most forms are bound to one or more tables

and queries in the database. A form's record source refers to the fields in the

underlying tables and queries. A form need not contain all the fields from each of the

tables or queries that it is based on. A bound form stores or retrieves data from its



underlying record source. Other information on the form, such as the title, date, and

page number, is stored in the form's design.

Reports

A report is an effective way to present your data in a printed format. Because

we can control over the size and appearance of everything on a report, we can

display the information the way we want to see it. Most reports are bound to one or

more table and query in the database. A report's record source refers to the fields in

the underlying tables and queries. A report need not contain all the fields from each

of the tables or queries that it is based on.



4. TESTING

“No man is perfect ”said a philosopher. Every human being is born with

certain imperfections and has to struggle to make himself performance “God Has

made the world imperfectly”, said a student of his guru, and he replied “Only to be

made perfect by you”. This is the case not with the human alone also with the system

he has designed.

The software, which has been developed, has to be tested to prove its

validity. Testing is considered to be the least creative phase of the least creative

phase of the whole cycle of system design. In the real sense it is the phase, which

helps to bring out the creativity of the other phases makes it shine.

TYPES OF TESTING DONE

Testing forms a core part of any project. There are various types of testing are

there. In this system we are done following testing

- White Box testing

- Black Box testing

- Unit Testing

- Integration Testing

- User Interface Testing



4.1 WHITE BOX TESTING

White-box testing, sometimes called glass-box, is a test case design method

that uses the control structure of the procedural design to derive test cases. Using

White Box testing methods, we can derive test cases that

(1) guarantee that all independent paths within a module have been

exercised at

least once

(2) Exercise all logical decisions on their true and false sides

(3) Execute all loops at their boundaries and within their operational bounds

and

(4) Exercise internal data structures to assure their validity.

4.2 BLACK BOX TESTING

Black Box testing focuses on the functional requirements of the software.

That is, black box testing enables the software engineer to derive sets of input

conditions that will fully exercise all functional requirements for a program. Black

box testing is not an alternative to White Box testing. Rather it is a complementary

approach that is likely to uncover a different class of errors than White Box methods.

Black Box testing attempts to find errors in the following categories

1. Incorrect or missing functions

2. Interface errors

3. Errors in data structures or external data base access

4. Performance errors

5. Initialization and Termination errors

Unlike White-Box testing, which is performed early on the testing process black-

box testing tends to be applied during later stages of testing because black-box



testing which is purposely disregards control structures attention is focused on the

information domain.

4.3 UNIT TESTING:

Unit testing focuses verification effort on the smallest unit of software

design-the module. Using the procedural design description as a guide, important

control paths are tested to uncover errors within the boundary of the module. The

relative complexity of tests and uncovered errors is limited by the constrained scope

established for Unit Testing. The unit test is normally white-box oriented and the

step can be conducted in parallel for multiple modules. The module interface is

tested to ensure that information properly flows into and out of the program unit

under test. The local data structure is examined to ensure that data stored temporarily

maintains its integrity during all steps in an algorithm’s execution. Boundary

conditions are tested to ensure that the module operates properly at boundaries

established to limit or restrict processing. All independent paths (basis paths) through

the control structure are exercised to ensure that all statements in a module have been

executed at least once. And finally, all error-handling paths are tested.

UNIT TEST PROCEDURES:

Unit testing is normally considered as an adjunct to the coding step. After

source-level code has been developed, reviewed, and verified for correct syntax, unit

test case design begins A review of design information provides guidance for

establishing test cases that are likely to uncover all errors. Each test case should be

coupled with a set of expected results.

Because a module is not a standalone program, driver and/or stub software

must be developed for each unit test. In most applications a driver is nothing more

than a “main program” that accepts test case data, passes such data to the module (to

be tested), and prints relevant results. Stubs serve to replace modules that are



subordinate to (called by) the module to be tested. A stub or “dummy subprogram”

uses the subordinate module’s interface, may do minimal data manipulation, prints

verification of entry, and returns.

Drivers and stubs represent overhead. That is both the software that must be

developed but that is not delivered with the final software Products drivers and Stubs

are kept simple, actual overhead is relatively low.

Unit testing is simplified when a module with high cohesion is designed.

When only one function is addressed by a module, the number of test cases is

reduced and errors can be easily predicted and uncovered.

USER INTERFACE TESTING:

An interactive interface is a system that is dominated by interaction between

the system and external agents, such as humans, devices or other programs. The

external agents are independent of the system, so their inputs cannot be controlled,

although the system may solicit response from them. An interactive interface usually

includes only part of an entire application, one that can often be handled

independently from the computational part of the application. The major concerns of

an interactive interface are the communications protocol between the system and the

external agents, the syntax of possible interactions the presentation of output, the

flow of control with in the system, the ease of understanding and user interface,

performance and error handling.

The dynamic model dominates interactive interfaces. Objects in the model

represent interaction elements, such as input and output tokens and presentation in

response to input event sequences, but the internal structure of the functions is

usually unimportant to the behavior of the interface.



5. PROJECT DESCRIPTION

System implementation is an important phase in a project. After analysis

phase, we come to a conclusion of, which modules are required and the system

requirements are also finalized.

Architectural design involves identifying the software components,

decoupling and decomposing them into processing modules and conceptual data

structures & specifying the interconnections among the components.

Software design is a process through which the requirements are translated

into representation of software.

A user must complete the sign-up process, which involves the completion of

form to be filled in by the user and to be submitted. Once the users are login with

their user id & password, they are allowed to.

Implementation of modules:

There are three modules in this project. They are

1. Master

2. Transaction

3. Search

Master Module:

Master module is again subdivided into

1. Member

2. Book Master

3. Magazine

Member:

The system will ask for the details like Type, Type Id, Type Name, Number

of cards and Return Days One book is given for each card.

Book Master:

The system will be denote what are available books we have, then it will

displays all the details. It includes the Access Number, Author Name, Book Title,

Publisher, Number of Pages, Edition, Price, Subject, Remark, and Number of cards

and Status. In this case if the book is lost it has to be paid by an amount of about two

times more than the actual price.

Transaction Module

The Transaction module is sub divided into

1. Book Issue

2. Book Return



Book Issue

The system will be maintaining all the appropriate details of issued books. At

the time of book issue the system will collect the following information from the

borrower. They are type name, member Id, Name, Department, no of cards and issue

date etc.For each card only one book is issued.

Book Return

The system will maintain all the appropriate details of returned books. At that

time of returning the system will fetch the following information from the system.

They are type name, member id, issue date, cards, actual return date and old fine

calculations etc. . In the case of delay the fine value for each day is about twenty-five

paise. In this case if the book is lost it has to be paid by an amount of about two

times more than the actual price.

Fine calculation

The system will maintain all the appropriate details for fine details of

members. In the case of delay the fine value for each day is about twenty-five paise.

In this case if the book is lost it has to be paid by an amount of about two times more

than the actual price.

Search

The Search module will be divided into

1. Book Search

2. Member Search



Book Search

The system will maintain all the appropriate details of books. At that time of

searching the system will fetch the following information from the system. They are

search type and type name etc. The management in the library may not know the

stock of books that are stored in the library. So the management uses this type

inorder to search the books whether book is on issue or not.Thus using this prosses

searches the books.

Member Search

The system will maintain all the appropriate details of members of the

library. .The management in the library may not know which member has taken the

book from the library. At that time of searching the system will fetch the following

information from the system. They are member type, number of cards and whether

the book is issued to the member or not etc.

9. FUTURE ENHANCEMENTS

Some of the future enhancements that can be done in this project are:

1. We can fetch all corresponding server information to another system in

another city using Three Tier Architecture.

2. Finding what are the books in which rack are computerized in future.

3. On line library facility can also be added in future.

4. Home delivery System will be included in future.



10. CONCLUSION

The project “OWEN TRUST LIBRARY MANAGEMENT SYSTEM” has

been designed and developed for Library process. The details of Library process

have been computerized. The next important feature is its user friendliness and easy

navigation. Flexibility of the system is also maintained. This is a client server

programming, user can easily maintain all Library process. Though the system has

been developed using modern approaches in software engineering, non-computer

professional with little knowledge can operate it.

This system has been divided into modules such that each module has

separate entity making modification easy without affecting the main design of the

system.

This system works in a fashion, which is very user-friendly and also gives

more option to the user. All the works that have to be done manually during the

examination has been computerized in a better way. The system is tested by possible

sample input and the performance of the system proved much efficient data

maintenance and retrieval is achieved much efficiently and satisfactorily.
