Service-oriented Workflow System Design And Implementation

With the development of the software technology and improvement of the informalization, people have much higher requirement for the software. The early software was used to calculate instead of people or some simple and repeated work. Then the main task of the software changed into dealing with the information data. The informationization bring a large amount of convenience that makes the departments declare the information through the Internet and make use of the workflow technology to achieve the office automation. But with the establishment of the information systems in enterprises, some new problem comes out in the office automatism. First, how to contact the business processes from different departments. Second, how to achieve the changes of the business processes according to the requirement. In order to solve these problems, I make use of service oriented workflow system in this paper.The main subject for this paper is studying the design, presentation and the application of the service oriented workflow system. The main research and achievement are as follow:First, this paper does deep analysis and research on the open source frameworks of the service oriented workflow system, Jbpm workflow framework, Axis2 web service framework. Meanwhile, I have made some changes for the Jbpm source code with a good analysis of it. Then it gets and introduces the integrated and distributed workflow control model. Integrated workflow control model is mainly on the purpose of the extensive problems of the latest business process in enterprise multisystems. Distributed workflow control model is mainly on the purpose of the integrated problems of the business process in enterprise multisystems. Then the paper introduces the application samples of the service oriented workflow system. Through such samples it made that how to solve the enterprise business process integration problems with the integrated and distributed workflow control models more clearly.Then based on these models, I design the service oriented workflow system's architecture and the modules and functions of it. Then using the Jbpm, Axis2 open source frameworks it made the system come true. The service oriented workflow system with open source framework will decrease the expending and enhance the efficiency of the enterprise business process development. It will make differences for the informationization and capability of competition of the enterprise.At last, the service oriented workflow system was used in the EPoS system to solve the enterprise business process integration and extention problems.
