MANAGING COMPLEXITY IN OBJECT-ORIENTED ANALYSIS

The current approaches in Object-Oriented Analysis have limitations on modeling complex real world systems because they require priori knowl edge about objects and their interactions before applying them. This m ay be practical in small systems and systems with clear domain knowled ge, but not in large real world systems with unclear domain knowledge. Our approach uses a stepwise refinement technique in a top-down manne r to the Object-Oriented Analysis stage with the application of use ca ses. This approach is especially good for new areas where we do not kn ow all the information in advance. We present the approach with an exa mple of its application to the B-ISDN service modeling and distributed systems.
