基于SOA的轻量级工作流中间件的研究与设计

随着企业信息化建设的不断深入,基于异构信息系统的集成正在成为研究和应用的一个热点。在解决异构系统之间的数据交互之上,探索如何从业务流程的需求出发,构建一个基于异构系统的工作流调度中间件更是成为研究与应用的一种趋势。本文以面向服务的构架为基础研究和设计了一套用于集成异构系统的工作流中间件。各个异构系统采用各自支持的数据交换方式,利用XML文件与中间件进行相互调用。各个异构系统将其能完成的业务功能按照一定的粒度进行划分,并将这些功能以服务的方式在中间件里注册,通过工作流引擎进行统一的调度以完成一个大的业务逻辑过程。

Research and Design on Workflow Middleware Based on Service Oriented Architecture

With the development of information technology applied in corporation,heterogeneous information system integration is becoming one of hotspots in the research field.In addition to the data exchanging between different heterogeneous,the workflow middleware which schedules all the service hosted by different heterogeneous to complete a business process is becoming a key role in heterogeneous information system integration.This paper describes the way to design and develop a workflow middleware based on Service Oriented Architecture in heterogeneous information system integration.Heterogeneous information system's function is divided according to some particle size and registered as service in middleware.Then middleware schedules and executes all the registered service according to business process.
