摘要: 基于信息论通信系统原始模型构造了由信码、动作和目标刻画的三维领域概念模型,给出了领域的精确定义.提出用于构造任意构件的基本单元——微构件模型,并在领域三维模型的信码-动作平面给出微构件的精确刻画.提出了基于软总线的一般领域构架建模方法.软总线支持构架内信息流与控制流的混合结构传输,支持把协作策略从功能服务中分类出来,简化领域构架的控制操作行为.以上方法应用于电子政务领域工程实践,已成功地构造了一个柔性软件生产平台(SoftProLine),用于开发一整套基层政府的电子政务应用软件系统,突出地体现了高质量、高效率、高柔性的技术特点,方便灵活地满足用户全方位的需求.

Abstract: Based on the communication system model in the Information Theory, a three-dimensional domain concept model is proposed to depict domain exactly. Thefirst dimension is information encoding format; the second one is action of information operation; the third one is atomic goal of information system. A micro-component model, which is the basic unit to construct arbitrary components, is proposed and depicted exactly in the projection on the encoding-action plane of the three-dimension model. Using the method of PAD(projection analysis of domain), a common domain architecture modeling method based on the soft-bus is proposed to resolve the problems in the modeling. The soft-bus can transmit the mixed structure of information flow and control flow in the architecture, divide the collaboration policy from the function services and predigest the control operation for domain architecture. The method above is applied in the e-government domainas an instantiation. SoftProLine, a flexible software produce platform, is given as a customizing tool to develop various e-government applications. It can satisfy the requirements of users with high quality, high flexibility and high efficiency.
