PREFACETo achieve excellence in the field of knowledge and skill requires

training with sound theoretical background. The well planned, properly executed, and objectively evaluated industrial training helps a lot in developing the good work culture. It provides linkages between student and Industry/Organization in order to develop practical approach on broad understanding of process and mode of operation of an organization.

During Training period, student get real first hand experiences on working in the actual environment. Most of the, theoretical knowledge that have gained during the course of their studies is put to practice test. For a student of Management, such training immensely helps in acquiring the best current knowledge.

I had the opportunity to have the real practical experience, doing my training in the Usha Martin LIMITED which has increased my sphere of knowledge and skill to a great extent. Now I am better equipped to handle the real things by undergone such training. The main aim of this training was to improve Knowledge as well as learn Organizational Behaviors.

I am thankful to Dr. Rupali Sharma (H.O.D, Deptt. Of Management), and Prof. P.K. Sharma (My Guide) for their support.

SynopsisIntroduction

This project has been undertaken as part of our curriculum for the partial fulfillment of our course. The job assigned by my project guide is to develop Library Management System.

Purpose The purpose of this document is to serve as the basis for:

1. Developing a computerized Library Management System for Officers and Staff member of the intuition for records entry, updation, maintenance and manipulation to take decision.

2. Automatic updation of records after data entry or deletion, thereby removing any discrepancy in the system.

ScopeThe scope of this system is to carry out the following:

Enter and maintain details of different books their category and status.

Enter and maintain details of employees. Status of availability of books in the Library.

Special features

9

(a) Security1. User password installed.

(b)Automatic updationThe data entry process makes room for automatic updation of

certain data on requirement basis.

Hardware & Software requirements

Hardware Requirements:

A Personal Computer with:-1. Minimum 128 MB RAM2. Minimum 40 GB Hard Disk3. Windows 98, NT, XP, Vista installed

Software Requirements:

Front End:1. Microsoft Visual Basic 6.0

Back End:1. Microsoft Access (Microsoft Office)

10

Introduction to Viual Basic 6.0:

Microsoft Visual Basic, the fastest and easiest way to create applications for Microsoft Windows®. Whether you are an experienced professional or brand new to Windows programming, Visual Basic provides you with a complete set of tools to simplify rapid application development.The "Visual" part refers to the method used to create the graphical user interface (GUI). Rather than writing numerous lines of code to describe the appearance and location of interface elements, you simply add prebuilt objects into place on screen. The "Basic" part refers to the BASIC (Beginners All-Purpose Symbolic Instruction Code) language, a language used by more programmers than any other language in the history of computing. Visual Basic has evolved from the original BASIC language and now contains several hundred statements, functions, and keywords, many of which relate directly to the Windows GUI.

Conclusion

A short and pain taking but highly knowledgeable journey comes to an end. The summer training in the USHA MARTIN gave us a great opportunity to learn things beyond our course.

We learn how to Analyze a system, how to design it etc. . Whatever we have read in our course, during the training we got the opportunity to implement those idea and we got a great practical knowledge. This project helped us to enhance the inner ability. We are confirm that project will help us in our career because learning never ends.

This thesis is devoted to computer analysis techniques in the development of the Library management system. For obtaining some proper results, a real model of the loading diagram has been build. On the basis of this load diagram analyses are performed. Finally, geometry is also optimized. The models used for simulation are real, taken from a reputed company USHA MARTIN Pvt.Ltd, Tatisilwai. This type of Library management system can be used in this company because of its technical benefits in most of the Library system applications. Because of its easier user interface it is very convenient for user to use and can be easily appended as to users needs. This software in made to fulfill all the modern library management systems copes with all the modern needs of the user.

During the simulation the file distribution of the software it was observed that it was easier to use and more effective. Also an effort has been made to meet the optimum shape needed to design them for an optimal operation. It can be concluded from the study that the nominal operation of this software is that it can face all the changes needed by the user and is made to easier management of a library .

Limitations

Time constraint: Time was always a constraint with this project to complete in time.

It does not contain any record of purchase of books.

Being coded in Visual Basic 6.0, the connectivity process was not easy.

Errors might creep up during implementation
