一种分布式构件目录库的设计与实现

The Design and Implementation of Distributed Component Catalog Database

在分布式计算平台上,各个专用的软件构件库对构件的表示以及组织形式上都有很大的差别,这样造成用户搜索和复用构件的困难。论文为管理分布式构件库提出了构件目录库的概念和模型。在对目录项(即构件描述信息)作了通用的定义后,设计并实现了构件目录库的支持工具,包括对构件信息的提取、存储、增加、删除、检索等一系列操作,满足不同网络环境下的用户定制软件的要求。

On the distributed computing platform,the difference of each specific component database is great in the term of presentation and organization of the components which makes it difficult for users to search and reuse them.This article introduces the concept and model of a component catalog database to manage the component database.After the definition of the catalog item - component description information,the support tools of the component catalog database are designed and implemented,including the abstraction,store,addition,deletion and retrieval of the component information.
