【摘要】 体系结构描述语言(architecture description language,简称ADL)是基于体系结构的软件开发的基础,便于表示求精的ADL,使得好的设计能够方便地导出好的实现.时序逻辑语言XYZ/E可在统一的逻辑框架下既表示静态语义又表示动态语义,因而基于XYZ/E的体系结构描述语言XYZ/ADL支持从高层级体系结构到低层级体系结构之间的逐步过渡.系统地阐述了XYZ/ADL的概念框架并用XYZ/E进行语义解释,介绍了如何用XYZ/ADL描述体系结构和体系结构风格.更多还原

【Abstract】 The architecture description language (ADL) is the foundation of software development based on software architecture. An ADL supporting stepwise refinement can make it more convenient that a good design leads to a good implementation. The architecture description language XYZ/ADL can support the stepwise transition from higher-level architectures to lower-level architectures, because it is based on the temporal logic language (TLL) XYZ/E, which can represent both dynamic semantics and static semantics under a unified logical framework. In this paper, the framework and syntax of XYZ/ADL is presented and its underlying semantics is explained using XYZ/E, and how to describe software architecture and software architecture style using XYZ/ADL is introduced.更多还原
