INTRODUCTION

I will start this project by describing the word “TECHNOLOGY” this word is rapidly changing day by day. Earlier where people were totally dependent on paper to store their data have now moved to the world of computers. Today we see everything is computerized and which is also getting enhanced day by day.

In earlier days people use to write the records for every transaction as a proof but as if now its all on computer. Hence we derive the library maintenance on computer which can be useful for maintaining, editing, saving the records. As we know it was very difficult to modify the information on the peace of papers, but in case of computers its an easy task and therefore we moved in this direction.

Our project is very useful. User is no longer required to check his register in search of records, as now it can be searched over the software by choosing some options. The user need not to type in most of the information. He/she is just required to enter the desired options. On the whole it liberates the user from keeping lengthy manual records. In a nutshell, it abates the work load of an organization.

In today’s world, no one likes to perform calculations on calculator or manually when computer is there. Every one wants his/her work to be done by computer automatically and displaying the result for further manipulations.

DESCRIPTION:-

This Library Management System is designed to make the library management virtual by making this live on computer systems, such helping the maintenance team, saving the time, and collecting the database. I have tried here to make this in the most famous programming language C++. Where I have used few of its inbuilt libraries to make the system more simplified and fruitful. This management system can help the library managers to save more then 1000 records, and modification and deletion at instant.

PROCESS FLOW:-

THE PROCESS OF SELECTED OPERATIONS HAS DIFFERENT SAVING, MODIFIENG, DELETING PROCESS FLOW

TESTING ( Screenshots of working program):-

Testing is very important part of programming as everything is executed and checked before we assure that our program is successfully generated and hence testing is needed.

In this context I have snapped few pictures of working model of my program.

THESE ARE THE FEW SCREENSHOTS OF WORKING MODEL. WHERE WE CAN ADD BOOKS AND MEMBERS AS WELL. LATER ON IN THE FOLLOWING PROGRAM WE ALSO COME ACROSS ISSUING AND RETURNING BOOKS OPTIONS.

Further Readings (Future Scope):-

The Working model of program can help lots of maintainer of library and can reduce their efforts. This program can be implemented in any kind of educational institutes and also several kind of library stores.

Still the program can be converted with lots of add on options and functionality, which can enhance the procedure of library handling in professional manner.
