研究软件体系结构的首要问题是如何表示软件体系结构，即如何对软件体系结构建模。根据建模的侧重点的不同，可以将软件体系结构的模型分为5种：结构模型、框架模型、动态模型、过程模型和功能模型。

-Research on software architecture of the primary question is how that software architecture, that is, how the software architecture modeling. According to the different focus of modeling can be the model of software architecture is divided into five kinds: structural model, a framework model, dynamic model, process model and function model.
