【摘要】 软件工程的目标是致力于提高软件生产效率和软件质量,如果每个应用软件系统的开发都从头开始,其中必然存在大量的重复劳动,软件复用是一条提高软件生产效率和软件质量的切实可行的解决方案,其出发点是应用系统的开发以已有的工作为基础,充分利用已有系统的开发中所积累的知识和经验进行新的开发,这样软件开发的重点就可以集中于应用系统中的特有构成成分上。通过软件复用,消除了包括分析、设计、实现、测试等软件开发过程中的重复劳动,提高了软件开发效率,通过复用已有的开发成果,避免了由于重新开发可能引入的错误,从而可以不断提高软件产品的质量。本文从软件体系结构的角度出发,对构件组装技术进行了一定得研究。提出了一个基于软件体系结构的、面向构件组装的构件模型。构件模型和构件组装两者有着非常紧密的关系,本文用XML文档对构件组装进行描述,在基于XML的构件模型上对构件进行组装。本文首先介绍了构件及其相关的技术,包括软件复用技术,构件技术以及各种构件组装方法等。其次,介绍了基于XML的构件模型。在基于XML的构件模型的基础上提出了一个基于XML的构件组装平台,对构建组装技术进行了深刻的分析。基于以上模型,本文开发出了一个构件管理和组装平台。该平台是一种插件式结构,可以方便的扩展平台所需要的功能。然后讨论了该平台所用的设计模式以及一些运行结构功能。更多还原

【Abstract】 The software development method that based on component reuse is one of the available ways resolve the crisis of software;Component-Based software engineering provide a systematic framework for the construction,maintenance,and evolution of software application and systems.Component-based software engineering has two fundamental elements a component model that defines the standard for the interaction and the composition of components,and a component framework that supports the execution of the components that conform to the model. A number of component models have been defined and many have been widely adopted in practice.These different component models have stimulated the rapid development of components by different developers, with the hope that eventually most components needed for application building will be available as off-the-shelf components.This paper is belong to software system frame,focus on researching componentcompositon.This dissertation advance a component model of software system frame and component composition.Component model and component composition have closeness relation.I make XML document descripe component composition and component composition.The first,this paper introduce component,include software reuse,component and component composition.then ,this paper introduce XML component model and component composition. We advance a component composition flat-building.It can insert to component,convenient extent function.then wo discuss flat-building design model and motion composition function.更多还原
