一种支持构件关系描述的构件库信息模型

Design of Component Library Information Model Supporting Component Relationship Description

随着软件复用技术研究的深入和软件构件库应用规模的扩大,构件库中构件的种类日益增多,构件间关系日渐复杂。这就需要对传统的构件库信息模型进行扩展,在完整描述构件自身信息的基础上,增加对构件间关系信息描述的支持。为了有效地发挥构件库的作用,提出的软件构件库信息模型在已有模型的基础上采用刻面描述机制并增加了对构件间关系的描述,利用该模型不仅可以有效地描述构件的各种信息,还使得用户可以根据构件之间的关系检索构件。

With the deepening of the research on software reuse technique and the development of component library scale,the categories of components stored in the library are growing rapidly,and the relations among components become more and more complex.Thus,the traditional component library information model needs to be expanded.Based on a complete component information description,the description of relations among components is added.In order to effectively play the role of library,a component library information model is presented.On the basis of the existing model,it adopts facet classification mechanism and adds relations among components.This model can be used to describe all kinds of component information effectively,and allow users to retrieve components according to the relations among the components.
