基于组件技术软件体系结构模型的设计

Software architecture models based on component technology

以往的结构模型系统结构复杂、设计周期长、不易实现系统的数据集成。从面向对象技术出发,根据可重用软件组件的特点及局限性,设计了软件体系结构基础模型和基于组件技术的软件体系结构模型,这种模型的关键在于一种高效的总线结构,使组件之间能以一个公共的接口互相连接,做到组件的即插即用,无缝集成。在这种模型的系统中,组件间的通讯链接数是线性的,并且由于各组件接口规范的一致性,通讯的复杂度大大下降,提高了组件的互操作性,达到了易于数据集成的目的。经过在大型数据处理系统中运行,证明该系统稳定性好,效率高,可广泛应用于大型复杂系统的数据集成。

Based on object-oriented technology and the software re-using technology,the basic models and the models based on component technology of software architecture are introduced.In this model,with the linear linking number and the interface consistency of different components,the complexity of communication reduces sharply.The application of these models in large complicated systems shows that they have good stability and high efficiency.
