摘要
针对可重构企业信息系统中业务构件的可重用性进行研究。本文首先结合设计模式和对UML元元模型的扩展,在对业务构件库中相似业务构件的共性部分和差异部分分析和抽象的基础上,提出了一种可重用业务构件模型———元构件;然后基于业务构件和业务构件集的形式化定义,对元构件进行了定义和语法描述,并对元构件的参数进行了详细设计,描述了如何通过元构件的编译参数和运行参数来提高业务构件的可重用性;最后给出一元构件应用实例。
The reusability of business component in reconfigurable enterprise information system is researched in this paper. First, meta component, a model of reusable business component, is presented, which is according to design pattern and extending UML meta-metamodel. meta component is based on analyzing and abstracting the commonness and difference of similar business components in business component library; then the formalization definition and syntax description of meta component are given,which are based on the formalization definition of business component and the set of business components, and the paper designs meta component's parameter in detail and describs how to improve the reusability of business component by the compiling parameters and the running parameters of meta component; last, an instance of meta component is presented.
