正如Perry和Wolf的预言，软件架构成为了20世纪90年代软件工程研究的焦点。由于

现代软件系统的复杂性，更加有必要强调组件化的系统，其实现被划分为独立的组件，这些

组件通过相互通信来执行想要完成的任务。软件架构的研究探索了如何以最佳方式划分一个

系统、如何标识组件、组件之间如何通信、信息如何沟通、组成系统的元素如何能够独立地

进化，以及上述的所有东西如何能够使用形式化的和非形式化的符号加以描述。-As Perry and Wolf' s prediction, software architecture has become in the 1990s the focus of software engineering research. As the complexity of modern software systems, and more necessary to emphasize components of the system, its implementation is divided into separate components that communicate with each other to perform through the desired task. Software architecture research to explore how best to partition a system, how to identify the components, how to communicate between components, information on how to communicate, how the composition of elements of the system can evolve independently, and above all things how to use the form oriented and non-formal symbols to describe.
