2. LIBRARY MANAGEMENT SYSTEM 2
ABSTRACT
Library Management System has tremendous importance in managing library
database most especially when dealing with large number of customers. This project shows
how important upgradation of library management system to e-library management is with
the concepts of showing relationships using primary keys and foreign keys in both SQL and
Microsoft Access. It also shows how different SQL is to Microsoft access though both are
used in maintaining and manipulating data in database but at some point have their
differences.

1.0 SQL DEFINITION
Structured Query Language (more often known as SQL) is a programming language
specially designed to help user in manipulating data that are stored in relational database
management system (RDBMS).
SQL has three basic languages.
1. Data manipulation language (DML)
2. Data definition language (DDL)
3. Data control language (DCL)

5. LIBRARY MANAGEMENT SYSTEM 5
1.1 DATA MANIPULATION LANGUAGE
These include the following:
1. Select
2. Delete
3. Update
4. Insert
1.2 DATA DEFINITION LANGUAGE
These include:
1. Create
2. Drop
3. Alter
1.3 DATA CONTROL LANGUAGE
These include:
1. Grant
2. Revoke

2.0 DATABASE AND MANAGEMENT SYSTEMS
A database is a collection of organised data. e.g. collecting information about all
employees in an organisation.
2.1 DBMS
Database management systems (DBMS) are applications specially designed for the
purpose of interacting with the user, the built database and other applications when capturing
and analysing data. There are lots of software systems that are general-purpose database
management system software which allows user to create, define, make querry, update and
administer databases. Some of this software includes Microsoft access, MySQL, SQLite,
FoxPro, dBASE, Oracle, FileMaker Pro etc.
2.2 RDBMS
Relational database management system (known as RDBMS) is an extension of
database management system which is based on relational modelling. It has become a
predominant choice of information storage in newly created databases used in personnel data,
logistics, manufacturing, finance etc. RDBMS has replaced the legacy databases and network
database used nowadays because it is easier and faster to use and understand
2.3 DIFFERENCE BETWEEN DBMS AND RDBMS
1. DBMS is used in just managing database while RDBMS is used to maintain relationship
among tables.
2. DBMS accepts flat file entry data type but RDBMS does not
3. RDBMS is used in complex applications while DBMS is used in simpler applications
4. RDBMS enforces the use and rules of foreign key but DMBS does not

7. LIBRARY MANAGEMENT SYSTEM 7
5. DBMS manage only small entry of data while RDBMS can manage both large and small
entry sets of data.
2.4 DIFFERENCE BETWEEN SQL AND ACCESS
1. SQL Server is a server based database while Microsoft Access is used as local database.
2. Access is used for small desktop size databases used by less than 5 users at the same time
and have a front end GUI system to design applications quickly while SQL Server is a
more robust system and is able to handle large amounts of users as well as data sizes and
does not have front end GUI system so it will require other development tools (Visual
Studios, .NET, VB, C++, etc.)
3. Access employs security based on the actual database settings. Each database can have
different security settings and employee lists. Logins are not tied to a users’ Windows
logon while in SQL, On Center Software recommends using Windows Authentication
when setting up an SQL database, that way, the users’ Windows security is transferred to
the database and only valid users can access the database AND the security is centralized.

8. LIBRARY MANAGEMENT SYSTEM 8
3.0 ABOUT THE SYSTEM
A library is a collection of organized information and resources which is made
accessible to a well-defined community for borrowing or reference sake. The collection of the
resources and information are provided in digital or physical format in either a building/room
or in a virtual space or even both. Library’s resources and collections may include
newspapers, books, films, prints, maps, CDs, tapes, videotapes, microform, database etc.
The main aim of this system is to develop a new programmed system that will convey
an ever lasting solution to the manual base operations and to make available a channel
through which staff can maintain the record easily and customers can access the information
about the library at whatever place they might find themselves.
The library has the following tables in its database;
1. Books (book_id, bookName, bookisbn, BOOKAUTHOR and bookedition)
2. Customer (customer_id, customername, customer_email, customer_address)
3. Staff (staff_id, staff_name, staff_address, staff_gender, staff_phone)
4. Branch (branch_id, branch_name, branch_location)
5. Issue (issue_id, issue_date, expiry_date, book_name, book_id)
6. Return (return_id, expiry_date, isuue_date, book_id)
The attributes are used to identify and keep track of each item (entity) in the library using
relationships within them which is established by the use of unique key identifiers (concept of
primary and foreign keys)

10. LIBRARY MANAGEMENT SYSTEM 10
The database store the daily activity carried out in the library, the database system
provides a supported form for the customer to make booking as well as to retrieve and modify
the existing records from the database. In order to have full data administration, this data can
be promoted, retrieved, manipulated and updated, to get a new record of the services rendered
in the library. Therefore, the library would have a new computerized system that would
record the information of the daily services carried out within the library and all its branches.
In order to overcome the current problem the library is facing, the following solutions
need to be deployed;
1. Computerized customer payment system
2. Digital ID for customers and staff
3. Use of a good RDBMS software in manipulating data in the database
4. RFID chip installed in books to ease transactions and security purpose.
5. Restrict access to database to only administrators and/or authorised personnel only

4.0 TABLES IN MICROSOFT ACCESS
Book table
Book table showing how data types are taken I n the book table

12. LIBRARY MANAGEMENT SYSTEM 12
Issue table
Issue table design view

13. LIBRARY MANAGEMENT SYSTEM 13
Customer table
Customer table design view, showing data types.

14. LIBRARY MANAGEMENT SYSTEM 14
Branch table
Above is the design view of branch table, showing how data are taken and how the data types
are defined.

15. LIBRARY MANAGEMENT SYSTEM 15
Return table
The return table has RETURN_ID which was taken as the primary key and a data
type set as number (autonumber). Other fields like BOOK_ID, ISSUE_ID, CUSTOMER_ID,
STAFF_ID are the foreign keys in the table having a data type of number.

16. LIBRARY MANAGEMENT SYSTEM 16
Staff table
In the table above, the staff_id is taken as the primary key and BRANCH_ID is the
foreign key in the table which has a data type number. Other fields like STAFFNAME,
STAFFADDRESS etc. are having a data type of text.

21. LIBRARY MANAGEMENT SYSTEM 21
Library branch table showing branches with their respective locations and IDs

22. LIBRARY MANAGEMENT SYSTEM 22
FORMS
Forms can be used to update records in a master table. For instance a new customer
comes in and makes a transaction (e.g. he was issued a book), a new form will be made under
the customer’s ID and update his record through the form (i.e. if he is an existing customer)
or create new record for him (if he is a new customer).

23. LIBRARY MANAGEMENT SYSTEM 23
Book form, for updating or creating new book record in the database in Microsoft access

24. LIBRARY MANAGEMENT SYSTEM 24
Staff form, also used to update record of staff in the database.

25. LIBRARY MANAGEMENT SYSTEM 25
Return of borrowed books form. Used for monitoring return of book in the database.

26. LIBRARY MANAGEMENT SYSTEM 26
This form has to be filled before giving any book out to any customer.

27. LIBRARY MANAGEMENT SYSTEM 27
Customer data form. It is made very simple and easy in order to capture the
customers’’ information when registering with the library.

28. LIBRARY MANAGEMENT SYSTEM 28
CREATING TABLES IN SQL AND INSERTING VALUES
Above is database titled library created in SQL using MySQL application. The
database library is created and a table (book) was created in it where various values were
assigned to it. Among the values is Book_id which represents the primary key of the table.
Insert values in done by using the command “insert into” where it allocates the written
value into the values assigned.

29. LIBRARY MANAGEMENT SYSTEM 29
Above is the view of the inserted vales into the table “book”. Viewing the values is
done by using the command “select *from book” after executing it, it displays all the inserted
values as seen above.

30. LIBRARY MANAGEMENT SYSTEM 30
Table above shows how to create another table (branch) in the database library.

31. LIBRARY MANAGEMENT SYSTEM 31
After executing, it shows the values inserted in the table.

32. LIBRARY MANAGEMENT SYSTEM 32
This is the relationship generated for the entire tables generated from the database

7.0 CONCLUSION
• SQL and Microsoft access are all database management application which is very well
used in the modern world in organising and manipulating a database.
• Though they have their differences like the GUI interface Microsoft access is having and
SQL doesn’t have, they all manage the database comfortable.
• Depending on the user or users, if an organisation have multiple users then they should go
for SQL server based application else if, they should go for Microsoft access.
• This project shows how to create tables in both SQL and Microsoft access and also how
to create simple data manipulation language and data definition language with how to
execute them.
• It also shows how relationships are established with the concepts of primary and foreign
key within a table.
• Lastly, the project shows how queries are created in SQL server, queries like the create
command, view, update, alter etc.
