Research in evolution and reuse of multi-leveled orthogonal software system architecture

The design, evolution and reuse of software system architectures are always important research areas in software engineering. In this paper, we first propose the concept of a multi-level orthogonal software system architecture, then describe a methodology of evolving and reusing this software architecture. Furthermore, we apply these concepts and methods to practical work, and are confident that they work well in reducing the complexity of software evolution (especially for large-scale software) and in enhancing the reuse rate
