OOA-(Introduction to OOAD)

Analysis emphasis an investigation of a  problem and requirements, raaather then a solution ''Analysis is abroad term best qualified as in requirement analysis (an investigation of the requirement ) or object analysis (an investigation of the domain objects)"
In the phase of OOA the typical question start with  What....? like "what will the classes in my program be?","what will be my progeam need to do?","what will each classes be responsible for?".

Hence,OOA cares about the real world and how to model this real world without getting into much detail. The OOA is an investigation of the problem and requirements, rather then finding a solution to the problem.

The primary task in OOA are:-

• Identifying Objects.
• Organize object
• defining the internal of the objects (object attributes).
• defining behavior of  the object (Object action).
• Describing how the object interact.
