基于XML的构件组装平台的设计与实现

Design and Implementation of a XML-based Component Assembly Platform

构件组装技术是支持软件复用的核心技术,构件组装平台的使用将系统开发的重点从程序设计转移到已有构件的选取、组装和部署;在构件模型的支持下,通过复用已有的构件,软件开发者可以"即插即用"地快速构造应用系统;在此,给出了一个基于XML的构件组装平台的设计与描述,并且根据构件自身特点和构件组装的需要自定义了基于XML的软件结构描述(SAD),其中包括基于XML的构件描述、连接子描述和组装结构描述,这些描述对连接子生成与构件组装提供了基本的信息支持。

Component assembly technology is the core technology of software reuse, component assembly platform successtully tultills the main points of system developing, such as component searching, component assembly and component transforming instead of program design. Under sustaining of component model, reusing component, software developer could quickly construct application system as plug and play. A design method and description of a XML-- based component assembly platformare are proposed here. According to component -self character and requirement of component assembly, a software architecture description; SAD （includes component description, connector description and assembly description） is defined in detail, which gives basic informational support for connector building and component assembly.
