BPEL 文档基于 DAG 自动生成框架的研究与实现

摘要

针对目前服务之间组合的复杂性，提出一种基于有向无环图的业务流程执行语言文档生成框架。通过对框架模型的解析，提出一种能够自动生成服务组合所需各种文档的改进框架及其算法，有效地隐藏了专业的业务流程执行语言知识和繁琐的服务组合流程。实践表明，该框架简单、易用，不仅能够清楚地反应服务组合之间的流程，而且还不需要 BPEL 专业方面的知识，减少了服务组合的工作量。%We proposed a DAG-based framework of Business Process Execution Language document generation for the complexities of compositions among current services.By resolving the framework model,we presented an improved framework,which can automatically generate various documents required for service compositions,and its algorithm,the professional knowledge of Business Process Execution Language and complex service composition processes are effectively hidden.Practice indicated that the framework was simple and easy to apply,the process among service compositions could be clearly reflected,and there was no need of professional knowledge of Business Process Execution Language as well,this reduced the work quantity for service compositions.
