1. INTRODUCTION

• The aim of this assignment is to design and implement a digital library, which will enable the library staff

to search for books and browse the information about the books as the publisher information, readers

information etc.

information about the readers.

and store the information about the readers in the registers and manage the information about the

reader is overwhelming consuming process.

1.4 ASSIGNMENT APPROACH

• To solve our problems in this system, we will use the following structured approach to achieve the

• system goals using the next steps in analysis and design phase :-

• We have taken the help by DFD so that data flow can be shown or seen.

2.1 CONTEXT DIAGRAM

• Prepare the context diagram, which it is the highest level view of the system, it contains only one

process and a number of data flows and also a number of sources. It is an overview of an organizational

system that shows the system boundaries, external entities that interact with the system and the major

information flows between the entities and the system.

3.0 CONCLUSION

• After prepared analysis and design for this system, we try to replace the manual system by automated

one. In over analysis we used high techniques to prepare a good design to be easy for implementation

phase, so we hope that this system will appear in a good case. This new system is required to match

new fast technology age for helping libraries requirement. The new system can be integrated with other

library's systems to get full benefit.
