Introduction. The aim of this project is to design and implement an online library, which will enable users to search for books and browse information about these books as the abstract, publisher information, cost, table of contents, etc. The database of the library based on one of the standardized systems for cataloging and classifying the books. We follow the standardization rules to assign subjects and sub-subjects codes, and to classify books under subjects and sub-subjects

Problem Definition and Objectives  1Problem statement. Retrieving books from a library is very important for many peoples. The main problem is to define whether this book is exactly what the user wants and where this book resides in the library (to go and pick). There is a need for designing an advanced search engine that searches a library database and returns a complete book record, including the shelf number on which the book resides.

Project 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 phases:-

1)Analysis phase:  In this phase we want to analyses the system and tray to explain the moving data between different components of the system. 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.

2) Design phase: Prepare the (ER) entity relationship diagram, which it is a data model that determines the relationships between several entities in the system. ER to relational data model mapping

3) Normalization. The normalization process takes a relation schema through a series of tests to certify weather it satisfies a certain normal form. Data Dictionary. (DD). It is a collection of data about data to provide information on the definition, structure and use of each data element an organization uses

4) Software requirements To develop this system we will chose the Oracle as a database and developer 6I as Oracle ’ s development tool... Oracle application may run on the same computer as the oracle server. Alternatively, applications and the tools supporting them may be run on a system local to the user (the client system), whilst the oracle DBMS runs on another system (the server system). SQL is the language used to access a relational database including Oracle. Oracle ’ s case tools:

CONT ….. We use Oracle ’ s case tools like developer 6I to maintain applications and to achieve the following objectives: Improve the integration of development activities via common methodologies. Help standardize the development process. Improve the management of the project. Simply program maintenance. Improve the quality of the systems developed.

A.1Conclusion. After prepared analysis and design for this system, we tried to replace the manual system by automated one. In our 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
