Pairing distributed systems with object paradigms results in a distributed object paradigm. Choosing the most efficient distributed object design is a multi-criteria decision problem. Performance is a key criterion that allows software developers to be able to select the object-oriented design that best fits their requirements and hardware limitations. However, investigating and evaluating the performance of Distributed Object Oriented (DOO) systems is a challenge due to the complexity of interactions among objects. Classical techniques and methodologies of performance analysis are either unsuitable or unnatural to capture the performance behavior of object-oriented systems while preserving object-oriented characteristics.; In this thesis, we investigate this problem and develop analytical models to study the performance of OO software that runs on single-node, distributed systems or pipeline architecture. We also develop a methodology to analyze and evaluate each model. The methodologies include: software computation, communication activities among objects, and object updating in case of the distributed environment.; The developed performance models can be integrated with the design phase to enable the software engineer to explore software restructuring, allocation alternatives partitioning or scheduling methodologies.; In many cases, the initial OO software does not have the best class distribution and may require restructuring. In this research, we utilize the performance-based model and the evaluation methodology to develop two new restructuring techniques; one for distributed object oriented systems and the other for software that runs on a pipelined architecture. The new techniques will efficiently restructure the OO software, fully exploit the system resources, and hence obtain better performance. | Keywords/Search Tags: | Software, Performance, Object, Systems, Distributed, New | | Related items |
