Object-oriented system development

Object-oriented system development - This book is intended to help the reader better understand the role of analysis and design in the object-oriented software development process. Experiments to use structured analysis and design as precursors to an object-oriented implementation have failed. The descriptions produced by the structured methods partition reality along the wrong dimensions. Classes are not recognized and inheritance as an abstraction mechanism is not exploited. However, we are fortunate that a multitude of object-oriented analysis and design methods have emerged and are still under development. Core OO notions have found their home place in the analysis phase. Abstraction and specialization via inheritance, originally advertised as key ingredients of OO programming, have been abstracted into key ingredients of OO analysis (OOA). Analysis-level property inheritance maps smoothly on the behavior inheritance of the programming realm.
