> 中文摘要: 目前的软件开发方法采用非结构化和非形式化方式建立构件模型,构件之间的关系是隐含的,并且缺乏严格的语义,不能有效地支持自顶向下的构件重用.利用范畴论定义构件之间的关系,使得构件之间的关系以及关系组合具有严格的语义.态射合成被用来跟踪不同抽象层次的构件之间的关系,利用体系结构设计模式精确地定义构件的组合关系和应满足的条件.范畴论支持图形化建模,可以使模型中的构件关系以及结构特征可视化,有利于模型的理解、跟踪和重用.形式化的构件建模方法适用于以重用为目标的软件开发.
Abstract:Existing software development approaches construct component model in an unstructured and informal way, and the dependencies among components are implicit and lack rigorous semantic. They don’t support top-down component reuse effectively. This paper tries to address these problems by using category theory to define the links between components, so that the links between components and the link compositions have rigorous meaning. The morphism composition is used to trace the relationships between components at different abstraction levels, and the architecture design pattern is used to define component composition and constrains precisely. Category theory supports the diagrammatic representation of component model that visualizes the relationships between components and the structural feature. The constructed component model is understandable, traceable, and hence reusable. Formal component modeling approach is suitable to the software development for reuse.
