一种总线型轻量级工作流引擎的分析与设计

Analysis and Design for a Lightweight Workflow Engine of the Bus Topology

针对目前常见的工作流管理系统存在结构复杂、灵活性差、缺乏柔性等问题,在工作流过程模型存储方式方面采用分层存储的思想将活动的静态属性信息与活动之间的交互信息相互分离,降低了过程模型的复杂度和耦合度.在此基础上,分析并设计了一种总线型轻量级工作流引擎LWEBT,该引擎将服务集中管理、组合,方便对服务和流程进行修改.以某高校教务管理系统的开发为例,验证了系统的灵活性和可扩展性.

In response to the problems of complex structure,poor flexibility and lack of dexterity commonly found in current workflow management system,the idea of hierarchical storage is employed to separate the static attribute information of activities from the interaction information between activities in the workflow process model storage mode,which can reduce the complexity and coupling degree of the process model.On the basis of this,a kind of lightweight workflow engine on the bus topology is analyzed and designed,which can not only make it possible to centralize the management and combination of the service,but also facilitate the modification of services and workflow processes.Taking the development and improvement of a university＇s educational management system as an example,the author verified the flexibility and expansibility of the system.
