Abstract
This thesis deals with the procedures related to analysis, design and implementation of
Library system. It is a low-volume real time transaction processing system intended for
small or medium size libraries. It is designed to provide such library functions as library
cataloging, patron registration, circulation and reference services based on a relational
databases management system.
This is an integrated system that contains both user component and the librarian
component. The goals are to enhance access and improve delivery of information in
various prints and non-print formats for resource sharing.
The aim of project is to create access to databases, accelerate documents to user and gives
us complete information about the library.

Introduction
1.1 An overview
Library Automation software, also known as an automated library management
system is a software that has been developed to handle basic housekeeping functions of a
library. The function may be either single function or integrated and realizing the
important role of library management system will play in planning and implementing
library automation projects.
It is an enterprise resource planning system for a library used to track items
owned, orders made, bills paid, and patrons who have borrowed and usually comprised of
a relations databases, software to act on that database, and two graphical user interfaces.
The basic purpose of this project to identify requirements for the library
management system which capable of supporting a union catalogue and other is
document retrieval from databases, the retrieval information contained may be
publication of books, journals articles, or technical report. With the exception of
automatic full text searching the information content of the documents is represented in
the form of a surrogate such as a set of index terms, the information in the documents is
accessed via the surrogates and the output of the system is a reference to a document
rather than the information itself.

1.2 Motivation Library corresponds to the very essential integrated part of any premier institute
which reveals the academic infrastructure capacities and potential to achieve novel work
in the field of education. Hence to maintain a good library is the huge task and I am very
much motivated to aim the library management system as my project work.
1.3 Objective The main objective of this project is provided complete solution for library
automation, management and accelerates transmission of document to user; generate
outcomes and evolutions via a library management information system
1.4 Overview of this thesis
In Chapter 2, I discussed Design methodology as UML, DFD, Entity-Relationship
and Sequence diagram. In chapter 3, I discussed keywords which are used for our project.
In chapter 4 we shall discuss overall set-up for running client-server architrature and how
a server listen client request and give response for a static page. In chapter 5, I discussed
our databases management (cataloguing) module, designed relational databases tables, its
relationship, mapping, constraints define, roll of primary key and its corresponding
foreign key. In chapter 6, I discussed our OPAC module which offered as an add-on
module. The main aim of this module related query searches. In chapter 6, I discussed our
Circular-Transaction module which used for the creation, storage, retrieval and
management of bibliographic records and/or indexes and defines the record format used
in the database and provides for authority control author, subject headings, useful for
Handles circulation activities such as lending, return, renewal, and place on hold manages
library materials - circulation type, location, status profiles, privileges; and other
transactions such as computation and payment of overdue fines, lost books etc. and in
chapter 7, I presented experimental results of our modules and finally in chapter 8, I
presented my conclusions.

Design Methodology
2.1 Use case diagram
A use case diagram is a type of behavioral diagram defined by the Unified
Modeling Language created from a use case analysis. Main purpose is to present a
graphical overview of the functionality provided by the system in term of actors, the goal
represented as use case and any dependedencies between use cases. It shows various
activities thus users can perform on the system, and system something performs a
function. The model shows dynamic aspects of system and user provides perspective of
the system.

2.2 Data Flow Diagram
A data flow diagram is a significant modeling technique for analyzing and
constructing information processes. DFD literally means an illustration that explains
the course or movement of information in a process. DFD illustrates this flow of
information in a process based on the inputs and outputs. A DFD can be referred to as
a Process Model. Additionally, a DFD can be utilized to visualize data processing or a
structured design.
A designer usually draws a context-level DFD showing the relationship
between the entities inside and outside of a system as one single step. This basic DFD
can be then disintegrated to a lower level diagram demonstrating smaller steps
exhibiting details of the system that is being modeled. Numerous levels may be
required to explain a complicated system.
Data flow diagrams can be used to provide a clear representation of any
function. The technique starts with an overall picture of flow of data and continues by
analyzing each of the functional areas of interest. This analysis can be carried out to
precise the level of details required. The technique exploits a method called top-down
expansion to conduct the analysis in a targeted way. The result is a series of diagrams
that represent the business activities in a way that is clear and easy to communicate.
Initially a context diagram is drawn, which is a simple representation of the entire
system under investigation. This is followed by a level 1 diagram; which provides an
overview of the major functional areas of the business. Using the context diagram
together with additional information from the area of interest, the level 1 diagram can
then be drawn.
The level 1 diagram identifies the major processes at a high level and any of
these processes can then be analyzed further - giving rise to a corresponding level 2
process diagram. This process of more detailed analysis can then continue through
4
level 3, 4 and so on. However, most investigations will stop at level 2 and it is very
unusual to go beyond a level 3 diagram.
There are different sets of symbols used for data flow diagram, depending on
accepted conventions, the symbol used in the data flow diagram are:
1. Process: A process is a unit of work that operates on the data the process may
be automated or manual, on -line, batch or real time. The symbol for a process
is a rounded rectangle.
2. Data flow: A dataflow is a named flow of data through a system of processes.
A data flow is shown as a directed line on the diagram.
3. Data store: A data store is a logical repository or data. It may be an automated
file, a paper file etc. A data store is shown as an open-ended rectangle.
4. External agent: An external agent is a source or destination of data. The
external agent is a source or destination of data. The external agent is depicted
by an overlapping rectangle.

2.3 Entities Relationship Diagram
An Entity Relationship Diagram is a graphical representation of entities and their
relationship to each other, typically used in computing in regard to organization of data
within databases or information system.
An entity is a piece of data-an object or concept about which data is stored. And a
relationship is how the data is shared between entities
2.3.1 What are Entities and Relationships?
An entity represents a discrete object. An entity is something that has a distinct
separate existence, In particular abstraction and legal fictions are usually regarded as
entities. In general, there is also no presumption that an entity is animate.
An entity could be viewed as a set containing subset. The word entity is often
useful when one wants to refer to something that could be a human being, Sometimes; the
word entity is used in a general sense of a being whether or not the referent has material
existence. Taken further, entity sometimes refers to existence or being itself..
A relationship captures how two or more entities are related to one another a
relationship is a specific connection between objects, entities or concepts. Typical forms
of relationship are social relationships between people, causal relationships between
events, and mathematical or theoretical relationships between components of a modeled
system.
2.3.2 Symbol used in (E-R) Diagram and its mapping:
In the E-R Diagram the symbol rectangles represents entity class, circle represent
attributes, diamond represents relationships
Manly three types of relationships may be between entities:
8
1 One-to- one: one instance of any entity X is associated with one other instance of
another entities Y
2 One-to-many: one instance of an entity X is associated with zero, one or many
instances of another entity Y, but for one instance of entity Y there is only one
instance of entity X.
3 Many-to-many: one instance of an entity X is associated with one, zero or
many instances of another entity Y, and one instance of entity Y is
associated with one, zero or many instances of entity X
Note : According our relational databases tables, relational schema table
Book_Details and table Borrower_Issue had relationships one-to-many,relation
schema table Book_Details and Borrower_Return had one-to-many relationships
and relational databases table user_type and user details had a relationship many-
to-many.

2.4 Sequence Diagram
A Sequence diagram depicts the sequence of actions that occur in a system. The
invocation of methods in each object, and the order in which the invocation occurs is
captured in a Sequence diagram. This makes the Sequence diagram a very useful tool to
easily represent the dynamic behavior of a system.
A Sequence diagram is two-dimensional in nature. On the horizontal axis, it
shows the life of the object that it represents, while on the vertical axis, it shows the
sequence of the creation or invocation of these objects.
Because it uses class name and object name references, the Sequence diagram is
very useful in elaborating and detailing the dynamic design and the sequence and origin
of invocation of objects. Hence, the Sequence diagram is one of the most widely used
dynamic diagrams in UML.
A sequence diagram shows, as parallel vertical lines, different processes or
objects that live simultaneously, and, as horizontal arrows, the messages exchanged
between them, in the order in which they occur. The symbol used in the sequence
diagram
: Stand for Object lifeline: A representation of the existence of an object over a
particular period of time
11
: Stand for Computing activation: The period during which an object activation is
actually computing (i.e. it is the top item on the stack).
: Stand for Lifeline node: A connection point in a lifeline.
: Stand for send message: Connects into object lifelines and acts as the source of
any type of message.
: Stand for Activation: The period during which an object is performing an action
either directly or through a subordinate procedure. The Activation time may include time
when it has control information on a stack, but during which control resides
: Flow of control message: A message that passes the focus of control from one
object to another.
Synchronous message: An instantaneous communication between objects that
conveys information, with the expectation that an action will be initiated as a result.

Implementation
Currently the system runs on a single machine and assumes that the required software
(like JDK, JRE.MicrosoftSQLServer2000, and Jcreators etc) is installed on the same
machine. The user is expected to compile and configure Library Automation Software
correctly before start
3.1 Keywords used For developing the project following keywords were used
• Generic Technology Keywords Databases and Java programming used for developing project
• Specific Technology Keywords Microsoft SQL Server 2000, HTML, and servlet (Apache Tomcat 5.5 versions) used for implementation.
• Project Type Keywords Analysis, Design, Implementation, Testing and User Interface. 3.2 The Front End (Java)
For developing the project the Java Development Kit (JDK) is being used as implementation language. Java is suited to creating general business programs rather than low level drivers, performance critical or operating system code. Typically it is used for accessing databases or writing networking system some of the main alternative language to java are C++, Visual Basic and the new language from Microsoft called C#. You will sometimes see a description of a language as C/C++ because C and C++ are closely related. C++ compilers will generally compile any valid C language but most developers take advantage of the Object Oriented nature of C++.
15
C++ has a reputation for being able to create lower level programs than Java or Visual Basic and so is a natural choice if you are programming drives or anything that involves getting “close to the metal” where performance is at a premium. Most programming is not of this type however and C++ does not come with a slandered set of libraries for creating graphical programs.
The C# language is the joker in the pack when selecting a language because Microsoft recognized that Java include some very good ideas and “borrowed” many of the concepts to produce a new language that blended many of the virtues of C++ and Java. Although there are projects to make C# available on platforms other than Windows, the main platform at the moment is Window and for commercial purpose it should probably be considered non portable. The good news is that C# is sufficiently like Java that if you learn the one it will not be hard to learn the other, By contrast Visual Basic has very little in common with C/C++ or C# 3.3 Back End (Microsoft SQL Server2000)
Back end the databases is built on Microsoft SQL Server2000 which support all SQL queries and which is compatible with a long list of platforms. The Microsoft SQL Server2000 databases server provides the ultimate in scalability, supporting the capacity to handle deeply embedded applications with a footprint of 1MB to running massive data warehouses holding terabytes of information. Platform flexibility is a stalwart feature of Microsoft SQL Server2000 with all flavors of Linux, UNIX, and Window being supported. And of course, the open source nature of Microsoft SQL Server2000 allows complete customization for those wanting to add unique requirements to the database server.
A unique storage-engine architecture allows databases professionals to configure the Microsoft SQL Server2000 databases server specifically for particular applications, with the end result being amazing performance results. Whether the intended application is a high-speed transactional processing system or a high-volume web site that services a billion queries a day, Microsoft SQL Server2000 can meet the most demanding performance expectations of any system. With high-speed load utilizes, distinctive, Microsoft SQL Server2000 offers all right ammunitions for today’s critical business system.
With over 12 million installations, the Microsoft SQL Server2000 community is huge. This community has an incredibly diverse talent pool around the global-able to provide
16
Assistance with virtually any development language or host environment. Virtually every system admin has used and set-up Microsoft SQL Server2000 installation at one point or another making it even more pervasive. It is easier to find good developers with knowledge of Microsoft SQL Server2000 then any other databases. 3.4 Platform (Linux/Windows)
Library Automation system on operating Systems that support the Microsoft SQL Server2000. The Linux operating system is prevalent on server system these days, and with good cause. It’s an excellent, open Source operating system, robust, and with a very wide range of features and utilities. Its efficient in operation and there are lots of people who know it and will support it .Linux is a computer scientist’s operating system still- in other words it’s really not got the ease and simplicity of operation

Chapter 4
User manual Following sections will show how to configure, and need for installation
client-server architrature 4.1 Before You Begin
In this section you will be guided through the compilation and configuration process of Library Automation System. It’s not easy but it won’t necessarily be hard Library Automation System need the following software to be pre- installed on your system. 4.2 Getting J2SE Development Kit (JDK)
The Java Development Kit (JDK) is a Sun Microsystems product aimed at Java developers. Since the introduction of Java, it has been by far the most widely used Java SDK. In the current time Sun announced that it would be released under the GNU General Public License (GPL), thus making it free software. When the Java SE Development Kit (JDK) is installed, the Java SE Runtime Environment (JRE) is installed, as well. The JRE can also be installed separately. Installation notes for the J2SE Development Kit (JDK), including system requirements and installation instructions, are available for the following platforms. Platform 32-bit Installation 64-bit Installation Solaris Operating System JDK for Salaries JDK for Salaries 64-bit Microsoft Windows JDK for Windows JDK for Windows 64-bit Linux JDK for Linux JDK for Linux 64-bit 4.3 Getting Java 2SE Runtime Environment (JRE)
The run time Environment, or JRE, is a software bundle from sun Microsystems that allows a computer system to run an application. The software bundle consists of the JVM and programming interface and (API).The API provides a set of standard class libraries. The virtual machine and API have to be consistent with each other and are therefore bundled together as the JRE. This can be considered a
18
virtual computer in which the virtual machine is the processor and the API is the user interface. Installation notes for the J2SE Runtime Environment (JRE), including system requirements and installation instructions are available for the following platforms. Platform 32-bit Installation 64-bit Installation Solaris Operating System JDK for Salaries JDK for Salaries 64-bit Microsoft Windows JDK for Windows JDK for Windows 64-bit Linux JDK for Linux JDK for Linux 64-bit 4.4 Java Servlet Development Kit
The java Servlet Development Kit (JSDK) contains the class libraries that you will need to create servlet .a utility known as the servletrunner is also included, which enables you to test some of the servlet thjat you create. Thus for executing the servlet program first download JSDK from sun Microsystems follow the above instructions for installation on your machine The directory c:\Jsdk2.0\bin Contains servletrunner.exe and update the path the directory c:\Jsdk2.0\lib contains jsdk.jar This Jar file contains the classes and interfaces that are need to build servlet. Update your Class path environment variable so that it includes c:\Jsdk2.0\lib\jsdk.jar 4.5 Start the servletrunner Utility
Open a command prompt window and type servletrunner to start the utility. This tool listens on port 8080 for incoming client request 4.6 Start a web Browser and Request the Servlet Start a web browser and enter the URL shown here http://127.0.0.1:8080/servlet/filename 4.7 Microsoft SQL Server 2000
Microsoft SQL Server is a relational database management system (RDBMS) produced by Microsoft Its primary query language is Transact-SQL an implementation of the ANSI/ISO standard Structured Query Language (SQL) used by both Microsoft and Sybase. Its a multithreaded, multi user SQL Databases
19
management system which has according to Microsoft SQL Server more than 10 million installations. Microsoft SQL Server also supports Open Database Connectivity (ODBC).
4.8 Executing for the First Time For Execution first time of Client –Server programming adopted following steps:
Installed Jakarta-tomcat-5.5.9 which is include some file folder for file directory Installed jdk-1_5__0_06 –window-i586-p Select the user variable as well as system variable value User variable name : CATALINA_HOME User variable value: C:\ Jakarta_tomcat-5.5.9 System variable name : JAVA_HOME System variable value : c:\jdk 1.5.0_06 Select the path name "C:\ProgramFiles\Java\jdk1.5.0_06\bin\javac.exe"-classpath "C:\Servlet\flles;C:\Servlet\jakarta-tomcat-5.5.9\common\lib\ant.jar;C:\Servlet\jakarta-tomcat-5.5.9\common\lib\servlet-api.jar" C:\Servlet\flles\ When we executing the first time is different than executing it for the subsequent times You may expect to see some like this In terminal: Java.io.FileFoundException:setting-servlet-api.jar(No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:Error)
You might have already guessed that it is not as easy as opening the wrapper and having the sweet candy (may be easier than that but) so we need to do few things first, such as: Getting Microsoft SQL Server 2000 root Password Using SQL to communicate with Microsoft SQL Server Creating a Database in Microsoft SQL Server Selecting a JDBC driver to Connect to Microsoft SQL Server
20
4.9 Getting Microsoft SQL Server 2000 Root Password
By default, Microsoft SQL Server 2000 wills we installed with root super-user without any password. You can connect to Microsoft SQL Server 2000 without requiring password or by keying in blank password. However if you have set the password for root we need that one.
4.10 Using SQL to communicate with Microsoft SQL Server 2000
In this section we explain how to create SQL queries and use them to build new databases and interact with existing databases. When Microsoft SQL Server 2000 is installed, a simple, text –based program called Microsoft SQL Server 2000 client is also installed to send SQL queries to Microsoft SQL Server 2000 client . For communicate with Microsoft SQL Server 2000 msjdbc.tar is required witch is include following jar files lib/msbase.jar lib/mssqlserver.jar lib/msutil.jar 4.11 Creating a Databases in Microsoft SQL Server 2000
To create a new empty database, use the following SQL query CREATE DATABASE database-name Where database-name is the name that you wish to give to the database. To see for yourself that a database was in fact created, use this SQL query: SHOW DATABASES You can delete any databases with this SQL query: DROP DATABASES databases-name Use DROP carefully because it is irreversible 4.12 Selecting a JDBC Driver to Microsoft SQL Server 2000
Short for Java Database Connectivity, a Java API that enables Java programs to execute SQL, statement. This allows Java programs to connect with any SQL- compliant databases. Since nearly all relational databases management system (DBMS) supports SQL, and because Java itself runs on platforms, JDBC makes it possible to write a single database system application that can run on different platforms and interact with different RDBMS. JDBC is similar to ODBC, but is designed specifically for Java programs, Whereas ODBC is language- independent. Presently only Microsoft SQL Server 2000 connector is available which is the official JDBC driver for Microsoft SQL Server 2000
21
The connectivity to Microsoft SQL Server 2000 given by the following JDBC Driver Class.forName(“com.microsoft.jdbc.sqlserver.SQLServerDriver”); Connection conn =DriverManager.getConnection (“jdbc: microsoft: sqlserver: //10.5.18.60:1433;User=satishk;Password=satishk12”);

Databases Management -Cataloguing
This use case allows enter the values in the databases a librarian enter the values using a static page the databases entry/updating/integrity is an import part of whole project thus a librarian enter the records of user, author, publishers, supplier, member, books, journals/Issue/Back Volume/Article/Report and other Non-book materials the selection of databases entry using enter a hot key. The librarian can view the current status of identification enter the values in the databases and also responsible for updating/deleting etc.
The creation of databases design based on the all tables and its corresponding constraints satisfy all table are in normal form which improve the efficiency of the databases. Java recognize some type of variables as numeric, string, Boolean, date, object and variant.
Numeric: Like other programming language java provide numeric variable. They are integers; single, double, byte, long and currency. Integer: Integer variable are used for the non functional values. It stores values in the range from -32768 to 326767. long data type is used for the range -2147483648 to 2147483647.single byte data type is used for representing number from 0 to 255.string variable are used to store string data type. Boolean: Boolean data type stores true/false value. Boolean variable are used in testing conditions Date: Date and time variables are stored internally in a special format, date variables are declared by following statements. Object: An object variable is used to refer any object in the application they are set to any of the object in the applications with set command. Variant: Special type of variables declares without any data type treated as variant they are capable of containing any type of value. if one can data type in variable declaration statement then variable will treated as a variant

5.2 Primary key and foreign key:
Every entity unless a weak entity must have a minimal set of uniquely identifying
attributes, which is called the entity's primary key. In the diagram underline attributes
with circle represents primary key.
In the context of relational databases a foreign key is a referential constraint
between two tables the foreign key identifies a column or a set of columns in one
referencing table that refers to a column or set of columns in another referenced table.
The columns in the referencing table must be primary key or other candidate key in the
referenced table. The values in one row of the referencing columns must occur in a single
row in the referenced table. Thus, a row in the referencing table cannot contain values
that don't exist in the referenced table except potentially NULL. This way references can
be made to link information together and it is an essential part of databases
normalization. Multiple rows in the referencing table may refer to the same row in the
referenced table. Most of the time, it reflects the one master table, or referenced table to
many relationship.
The referencing and referenced table may be same table, i.e. the foreign key refers
back to the same table. Such a foreign key also known as self-referencing or recursive
foreign key.
5.3 Syntax of Foreign key:
Foreign keys are defined through a FOREIGN KEY constraint. The syntax to add such a
constraint to an existing table is defined as shown below.
ALTER TABLE <table identifier> ADD [ CONSTRAINT <constraint identifier> ] FOREIGN KEY ( <column expression> {, <column expression>}... ) REFERENCES <table identifier> [ ( <column expression> {, <column expression>}... ) ]
26
[ ON UPDATE <referential action> ] [ ON DELETE <referential action> ]
In our relational databases design omitting the column list in the REFERENCES clause
implies that the foreign key shall reference the primary key of the referenced table.
Foreign keys can be defined as part of the CREATE TABLE SQL statement
CREATE TABLE table_name ( id INTEGER PRIMARY KEY, col2 CHARACTER VARYING(20), col3 INTEGER, ... CONSTRAINT col3_fk FOREIGN KEY(col3) REFERENCES other_table(key_col) ON DELETE CASCADE, ... )
If the foreign key is a single column only, the column can be marked as such using the
following syntax:
CREATE TABLE table_name ( id INTEGER PRIMARY KEY, col2 CHARACTER VARYING(20), col3 INTEGER FOREIGN KEY REFERENCES other_table(column_name), ... )
5.4 Participation constraint and key constraints:
In E-R databases table If all entities in an entity set must participate in the
relationship set Called a participation constraint and If each entity of the entity set can
participate in at most one relationship in the relationship set, an arrow is drawn from the
entity set to the relationship set. This is called a Key constraint.
5.5 Associative entity and Unary Relationships:
Relationships between two entities with a many-to-many relationship called
Associative entity and a relationship between the rows of a single table known as Unary
Relationships.

Online Public Access Catalog (OPAC)
The Online Public Access Catalog offered as an add-on module that is integral
with the cataloging module. The aim of this module is Accelerate Transmission of
Documents to Users due to help of this module a user as well as librarian staff can query
for own related query documents. The most query related to this module may be simple
search, advanced search, addition search, search by unique number, search by accession
number and journals search and see the current status of book either issued or not. Thus
most integrated library systems offer a browse-based OPAC module as a standard
capability or optional feature. Thus this module helpful for search for beginners and
query builders for advanced users.
6.1 Simple Search
This search allow single interface to all the resources a users and its members
Enter a word(s) from any of the searchable fields such as author, title, subject, unique
number(ISBN),accession number/account number, publishers etc. The search may also be
restricted to a specific field with an option to form a phrase. In this search a user can
search different query corresponding your string for example using exact word, any of
word ,ending word, initial word, and all word corresponding own input string the search
may also restricted through input string hence a user or others may be search own query
through Title, Search by Author, search by ISBN number ,search by Account/accession
,publishers and search by subject name, hence this types of search allows single
interface to all resources, multilevel sorting facility of search result and user
define/customized search result which are features of this search.
6.2 Advanced Search
An interface allows for development of complex search strategies using Boolean
operators like 'OR, ‘AND’, and 'AND NOT' between keywords in various fields. Hence a
28
user can interact for searchable search in advanced your input string using Boolean
operators, mostly this modules and query builder for experts using Boolean and logical
operators, and exporting search result in various file formats which are essential feature
of this search
6.2 Additional Search
An interface to develop search strategies using word(s) from various searchable
fields with an implied 'AND' operator.
6.3 ISBN Search
Its an also a interface where a user can search with a unique field, and search may also be restricted to a specific field with an option to form a phrase 6.4 Accession Search
Its an also a interface where a user can search with a unique field as search by
Accession/Account Number
6.5 Journals
The Serials Catalogue may be browsed, and on selecting a journal, details
including the holdings (both bound volumes and loose issues) are displayed. Basically
this option used for searching journals/research paper using by searchable fields
6.6 Help
Basically this option useful when a user and its member feel any difficulty
corresponding own query, option and other in this case user can help, to go option value
help, click Help menu a dialog box which is look like will we appear for window help.

Chapter 7 Circular-Transaction The aim of circulation module used for the creation, storage, retrieval and
management of bibliographic records and/or indexes and defines the record format used
in the database and provides for authority control author, subject headings etc.
Usually there are two different interfaces for search and retrieval of the electronic
catalog: one used by the catalogers that allows them to maintain the library database and
one provided for users that allows them to search and display the results through Online
Public Access Catalog .
This module useful for Handles circulation activities such as: lending, return,
renewal, and place on hold Manages library materials - circulation type, location, status,
patron type, profiles, privileges; and other transactions such as computation and payment
of overdue fines, lost books, etc. It may have added value functions like import, export,
and backup and restore functions for the databases, inventory and report generation. It
may support integration with security systems that complement the self-check-in and
checkout features of the circulation module. The main function of this module are-

Conclusions
60
The Library management system process made computerized to reduce human
errors and to increase the efficiency. The main focus of this project is to lessen human
efforts. The maintenance of the record is made efficient, as all the record is stored in the
access databases through which data can be retrieved easily. The navigation control is
provided in all the forms to navigate through the large amount of records. If the numbers
of records are very large then user has to just type in the search string and user gets the
results immediately. The editing is also made simple. The user has to just type in the
required field and press the update button to update the desired field. String and user gets
the results immediately. The editing is also made simpler. The user has to just type in the
required field and press the update button to update the desired field.
The books and students are given a particular unique ID no. so, that they can be
accessed correctly and without errors. Our main aim of the project is to get the correct
information about a particular student and books available in the library.
The problems which existed in the earlier library system have been removed to a larger
extent and it is expected that this project will go a long way in satisfying user’s
requirements. The computerization of the library management will not only improves the
efficiency but will also reduce human stress thereby indirectly improving human
recourse.
