Performance-based modeling for object-oriented software

Object-Oriented (OO) software brings new issues in software engineering. Information systems are more naturally expressed in an OO way. Choosing the appropriate OO model is a multi-criteria decision problem. Performance is a key criterion that makes software developers able to select the OO system that best fit their requirements. Classical techniques and methodologies of performance analysis are either unsuitable or unnatural to capture OO performance behavior. In other words, these classical techniques cannot work directly and at the same time preserve the OO features such as encapsulations, information hiding, inheritance and polymorphism. This paper presents an analytical performance model that analyzes OO software and introduces the time cost evaluation methodology based on that model.
