Here we are trying to develop, discuss, and evaluate object-oriented model of Dhaka university library system that, will handle:

The bookkeeping aspects of a library.

Administration system of the library.

User browsing facilities and circulating.Acquisition of books, manuscript, journals.

IntroductionIntroduction

“Object-oriented software construction is the software development method which bases the architecture of any software system on modules deduced from the types of objects it manipulates.” (Meyer, 1997)

In an object-oriented language, the types of objects are described by classes. These classes should be developed in a way that makes them easy to understand, maintain, and reuse.

IntroductionIntroduction

CRC: Class-Responsibility-Collaborator.

CRC cards allow a useful early check that the anticipated uses of the system can be supported by the proposed classes.

A responsibility is something a class takes care of; a service the objects of a class provide for other objects.

A collaborator is another class "helping" to fulfill a specific responsibility.

Being the largest library in Bangladesh, Dhaka university library system has a very complex structure. We tried our best to define a complete class structure of the library system through the use of CRC cards.

There may be some overlapping or fault in the identification of the class structure, further revision and modification can be done to define a complete structure.
