摘要
针对中轻量级领域类库构造中,缺乏构造技术支持及管理维护机制不完善的问题,提出了三层分治结构(Triple-CommuneArchitecture)的领域类库模型,从类部件的功能特征和应用层面,对类库进行横向分类和纵向划分,确定其结构组织形式;采用同源类链式继承机制,解决类库的扩展及版本升级问题;利用自定义的类部件形式化描述语言,对类库进行形式化描述,对类部件的属性、方法、关系以及其他相关信息进行定义,从而完成类库的维护和管理.在ERP类库原型系统研发中表明该模型提高了软件复用和开发的效率.
For solving the construction technique problems in mid-scale domain oriented class library, a model based on Triple-Commune Architecture （TCA） is proposed. Its hierarchical structure is sorted in layer and divided in tier by the component＇ s function and domain. The class library extension and edition upgrade problems are solved by providing a kind of homology mechanism. By defining a kind of formal description language are described which , the class component＇ s attribute, method, relation and other relevant informations facilitate the maintenance and management of the class library. The development of the prototype system of ERP shows that the method improves the efficiency of software reuse and shortens the cycle of software development.
