Web服务在工作流设计中的应用

The Workflow Model based on Web Services Technology

工作流技术是近年来在计算机应用领域中发展最为迅速的新技术之一,实现了系统中应用逻辑与过程逻辑的分离,是实现业务流程自动化的关键技术。Web服务是新一代的Web应用程序,是一类可通过开放的Internet协议访问的软件组件,代表了组件技术和Web技术的结合。Web服务以其开放性、良好的互操作性、语言和平台的无关性等优点,成为解决异构系统集成的首选。得到了大多数软件厂商的支持,具有广阔的应用前景。首先讨论了Web服务技术和工作流技术各自的特点和优点,分析了两种技术结合的可能性,并在此基础上提出了基于Web服务技术的电子政务工作流模型系统,并给出了具体应用案例。

As one of the most rapidly developing new teehnologies in recent year, workflow techlonology implements these paration of the application logic and process logic in information systems, it is the key technology to achieve business process automation. Web services is a new kind of Web application, is a kind of software groupware that can be visited through the open intcrnet protocol, and represents the integration of groupware technology and Web technology. Because of such advantages as open, operate mutually, the irrelation of language and platform, etc. , Web services has been the first solution in isomerous system integration field. It has been supported by most software manufacturers and has a wide application prospect. This thesis discusses respective characteristic and excellency of Web services technology and workflow technology, analyze the probability of the integration of them, prompt the E-government workflow system model based on web service technology, and provides the design and implementation ofthe main part in the model.
