Performance-based modeling for distributed object-oriented software

Information systems are basically distributed while object oriented brings new issues in software engineering. Pairing distributed systems with object paradigms results in a distributed object model. Choosing the appropriate distributed object model is a multi-criteria decision problem. Performance is a key criterion that makes software developers be able to select the object-oriented system that best fit their requirements. Classical techniques and methodologies of performance analysis are either unsuitable or unnatural to capture performance behavior of object-oriented (OO) systems. In this paper, we present performance-based model for distributed object-oriented software (DOOS) and a methodology to analyze and evaluate its performance. The new model evaluates the overall time cost of DOOS system considering the communication overheads while preserving the OO features such as encapsulations, information hiding, inheritance, etc.
