We mainly discuss and make some contributions to the problems such as distributed architecture of WfMS, XML Process Definition Language, description and management of the workflow relevant data, encapsulation and transfer of parameters, agent for invoking extern application etc. 本文在分布式工作流系统体系结构、XML过程定义语言、数据变量描述与处理、参数封装与传递以及外部应用调用代理等方面做了一定的探讨与创新。
In particular, it discusses the design pattern of MVC based on Struts and the architecture of W-Flow, and using the XML Process Definition Language ( XPDL ) to implement Workflow Definition Interchange ( Interface ). 讨论了用Struts来实现WFlow的MVC设计模式、WFlow的设计模型与系统架构,并用XPDL实现过程定义接口。
The meta-model is the basic architecture of all the object-oriented frameworks for the specific automatic test system, described by the Interface Definition Language ( IDL ) that is independent on the specific programming languages. 这个元模型是各种自动测试系统面向对象框架的基础体系结构。
