敏捷信息系统建模

敏捷信息系统是具有可重构能力的快速适应性系统。为了实现信息系统的敏捷性，采用规范化方法建立系统模型是其核心所在。本文在深入分析企业业务活动本质特征的基础上，运用面向对象方法、企业过程重组（ＢＰＲ）的基本思想及统一建模语言（ＵＭＬ）的表示方法，分析了敏捷信息系统模型的基本要素及其相互关系，给出了系统的模型结构。该模型结构不仅反映了企业业务活动中相对稳定的部分与随环境变化的部分，明确了两部分之间的相互关系，还将信息系统开发过程中的信息有机地集成起来，为实现快速的系统重构奠定了基础。

Agile information system modeling

Agile information system is the one of re constructivity and fast adaptability. The key of developing agile information system is building system model by formal methodology. Based on the deep analysis of the characteristics of enterprise business activities, both the fundamental constructs and their inter relationship of the agile information system were presented. In terms of the methodology of object oriented, the principle of Business Process Reengineering (BPR) and the notation of the Unified Modeling Language (UML), the model structure of this kind of system were outlined. The system model structure not only substantially differentiate the relatively stable and unstable aspects of the business activities, but also explicitly reflect the relationship between them and integrate the information of the system development as well, which is the foundation of the system reconstruction rapidly.
