SYSTEM OVERVIEW Library Management system can manage all the happenings of the Library. Book transactions including Book Registration, Stud Studen ents ts Regi Regist stra rati tion on,, Book Book Issu Issuin ing, g, Curr Curren entt Stat Status us of a part partic icul ular ar book books s etc. etc. can can be very very easi easily ly hand handle led d by this this module. Overall this system can be very helpful and it can make things easier The Library Management System is designed & developed for a receipt and issuance of books in the library along with the student’s details. The books received in the library are entered in Books Entry form and the new student is entered in the student entry form. When the student wants to get the desired book the same is issued on the availability basis to the student. The issuance and due date for the returning of the book is also entered into the Book Issue form under third menu Book Issue. The student has to pay the fine if any on the basis of no. of days delayed deposit of the book in the library.

PROBLEM DESCRIPTION Our project on developing a program to implement LIBRARY MANAGEMENT was encoded using C++ language The program is capable of performing the following tasks:
DATA SECURITY The data regarding books is password protected and the file can be opened only by librarian. ADDITION OF BOOKS It can feed the details about the book into the system and save it as a file. UPDATING BOOKS DETAILS It can change the details about the books any time. SEARCH A BOOK It can search for a book, if name of the book is provided. DELETING A BOOK It allows librarian to delete a book. •

The aim of this program is to fully automate the complete process of school of school library. library. Having taken into account a number of practical issues, it was felt the inclusion of the following features would be essential to make it user friendly. Menu •

PROCEDURAL DESIGN Void userpage(); Here the user-computer interface is handled. The user is allowed to issue a book, search for a book and view all the books available in the library.
Void libpage(); Here the librarian-computer interface is handled. The librarian is allowed to add, delete, modify, and view user details.
Void searchbook(); Here the function searches for the book in the file and reports to the user or librarian.
Void addbook(); Here the function allows the librarian to add new books to the already existing file.
Void delbook(); Here the function allows the librarian to delete a book from the file.
Void modify(); Here the function allows the librarian to update the details about the book like code, author’s name and price.

LIMITS OF THE PROJECT The
password cannot be changed within the program
The
program will accept two books having the same code.
Since
the display is restricted to a single screen, too many books cannot be accommodated.
31
FUTURE EXTENSIONS A
more attractive, user user friendly and compact compact interface is planned.
Provision
for individual profile and accounts for users with password protection.
A
more diverse classification classification of books, based on languages.
Error
- auto correcting capable inputs at all stages.
