Thus, how to efficiently develop extensib le, maintainable and adaptable software occurs to be an urgent problem. The comp onent-based software development technique is a better method to solve the prob lem. In this paper, we first discuss the concept, description method and some fa miliar styles of software architecture, and then analyze the merits of using the software architecture to guide the software development. We also present a gene ral design method for component. Its applications are finally provided.展开更多
