Abstract

With the development of Service Oriented Architecture (SOA), Web services have been adopted as the system integration solution by more and more enterprises. The greatest value that SOA brings to these enterprises is increased business agility. Thus, it is a key issue of successful SOA solutions to provide a dynamic Web service composition approach to facilitate business innovation and adapt IT to today’s fast changing markets. In this paper, we propose a model-driven approach for dynamic Web service composition. First, we define two UML models to modeling Web services and business processes, as well as describing the semantics of Web service functionalities and business process requirements. Then, we generate Web service and business process implementations from these two models automatically by following our predefined mapping patterns and transformation rules. Finally, by performing ontology-based semantic matchmaking, the qualified web services can be dynamically selected and bound into the business processes. A prototype system has been developed and is also delivered to demonstrate the effectiveness of our approach.

动态Web服务组合的模型驱动方法

随着面向服务体系结构(Service Oriented Architecture, SOA)的发展，Web服务作为系统集成解决方案被越来越多的企业采用。SOA给这些企业带来的最大价值是提高了业务敏捷性。因此，提供动态Web服务组合方法以促进业务创新并使it适应当今快速变化的市场是成功的SOA解决方案的一个关键问题。在本文中，我们提出了一种用于动态Web服务组合的模型驱动方法。首先，我们定义了两个UML模型来建模Web服务和业务流程，以及描述Web服务功能和业务流程需求的语义。然后，我们按照预定义的映射模式和转换规则，从这两个模型自动生成Web服务和业务流程实现。最后，通过执行基于本体的语义匹配，可以动态选择合格的web服务并将其绑定到业务流程中。一个原型系统已经开发出来，并已交付使用，以证明我们的方法的有效性。
