摘要
软件体系结构被看成是现代软件技术的重要因素之一 ,而一个软件系统结构的关键就是它可以分解成组件和组件交互的规格说明。扩展事件踪迹图 (ExtendedEventsTraces ,EETs)是一种用来描述组件交互的图形技术 ,它允许我们用图来定义结构中经常发生的交互模型 ,并且在多种上下文中可实例化 ,因而可以重用。虽然EETs的图形表示很直观 ,但是语义不够精确 ,因此 ,在本文中将使用形式规格说明语言Z来形式化EETs。并且 。
Software architecture is considered as one of the keys to modern software technology,and a crucial aspect of the architecture of a software system is its decomposition into components and the specification of component interactions.Extended Events Traces in a graphical technique for the description of such component interactions.It allows us to define interaction patterns that occur frequently within an architecture,in the form of diagrams.The diagrams may be instantiated in various contexts,thus allowing reuse of interaction patterns.The graphical represent is intuitionistic,but the semantic isn't precise enough.Accordingly,we will formalize EETs using formal specification language Z,and give several examples in the paper.
