基于三层模型的系统架构及建模设计

System Architecture Based on Three-tier Model and Modeling Design

结合工作流在传统SOA模型的基础上引入逻辑层,从业务的视角出发构建了基于SOA的三层模型,提出一种基于SOA动态模型的应用系统开发架构,完成业务组成的分析、业务流程的描述及相应构件的提取,并参考CPU结构完成流程引擎的设计。该模型在解决业务规则的快速扩展及应对风险的能力方面可以获得更大的空间,支持业务应用不断创新的需求。

Combined withworkflow technology the features of a good division of tasks and control, introducing logic layer on the basis of traditional SOA model, building a three-tier model based on SOA from the perspective of the business. Proposed a new framework development based on SOA dynamic model, complete the analysis of the composition of busi- hess, the application layer Languageof Business processes and the extract of the corresponding components and the de- sign of the process enginewith reference to the sequencer.Compared to traditional systems development methods based on static models, the model can get more space in their ability to solve the rapid expansion of business rules and deal with risks, support applications system of innovative business demand.
