软件组件获取方法的研究

The Research of the Retrieval Method of the Software Component

基于组件技术的应用开发(CBD)可以有效地减少开发成本和复杂性,并可以很大程度地缩短开发周期,提高软件质量。其中一个关键的问题就是如何能使重用者能够在因特网上准确、快速地查找到适用的组件;而这取决于科学的分类方法对各种各样的组件进行分类和管理,以及高效准确的搜索查找方法。文章对传统的分面分类法(Facetedclassification)进行了修改和扩充,在此基础上提供了一个新的分类体系对组件库进行科学地分类和管理;同时针对组件查找问题,提出了体系分类法,并实现了一个基于此分类法的用于软件组件的专门搜索引擎。

The Component-Based Development（CBD） helps us to effectively reduce the cost and the complexity of the development of the software systems,curtailing the development cycle,and enhancing the quality of them.The key problem is how to enable the reusers to find and get the suitable software components quickly and precisely on Internet; and this depends on the scientific classifying method for the classification and the management of the various components,and a highly efficient and precise searching method for them.In this paper,some modification and extension are pursued on the traditional classifying method （Faceted Classification） to provide a new classifying system,by which we classify and manage the multifarious components on Internet into a component repository. Meanwhile,the Systematic Classification is adopted here to provide the descriptive information of the software components for the special search engine.
