基于MDA的工作流建模技术的研究与实现

Research and Implementation on Workflow Modeling Technique Based on MDA

为提高企业Web应用系统开发效率,弥补模型驱动架构在业务逻辑建模方面的不足,提出一种基于模型驱动的工作流建模方法。以Petri网为理论基础,提出基于XML的工作流过程定义,并将描述工作流模型的XML作为平台无关模型的一部分送交MDR环境来解释执行。实现了业务流程的可配置,极大提高了Web应用系统开发效率。应用实例表明,可以实现业务流程的自动生成,满足企业业务流程快速开发部署和灵活变更的需求。

To improve development efficiency of Web applications of enterprises and make up the deficiencies of business logic modeling of MDA（model driven architecture）,a workflow-based model-driven modeling method is proposed.Based on Petri net theory,XML is used to describe business processes as part of the PIM（platform independent model） of MDA.An environment called MDR is responsible for executing the PIM.With the technology,business logic is configurable which greatly improves the development efficiency and meet the rapid development and flexible changing needs of Web applications development.
