The Research And Implementation Of Process-Based Service Integration System

With the development of economy, the business interact with enterprises in the upstream and downstream enterprises frequently. The traditional office automation system based on C/S model is isolated and can’t satisfy with the needs of today’s enterprise. Now, the business of enterprise updates fast, scopes widely, interacts with the third parties frequently. According to these features, companies need a designing scheme which will integrate multiple office systems and it also can interacts with third parties. According to the requirement, software developers need thinking a designing scheme how to integrate office automation system such as OA system, financial systems and other enterprise office systems, how to complete data sharing and business collaboration with third parties enterprises.Process-based service integration system which the paper covers is a part of the national project “the research of the E-commerce platform based on power industry supply chain collaboration”. The purpose of the project is to study the construction of process-based application system. The core of the system is model. Though the modeling, developer quickly construct office application system to satisfy the enterprise’s needs of making a timely response to the business change. In addition, the system implements transformation of process to service, the interaction between the services. These functions can meet the needs of enterprise business and the needs of frequent interaction with the outside world.The process-based service integration system adopt the service-oriented Architecture, combine with workflow and Web service together. We choose Workflow as main technique of the process-based service integration system to construct a workflow management system. The system consists of two parts, the one is service development system, and the other is service operating system. Service development system mainly consists of three parts. The three parts are data modeling tool, form modeling tool and process modeling tool. The function of data modeling tool is responsible for the construction of classes and properties of classes. The form modeling tool is use to custom the table.The process modeling tool is responsible for the process customization. Depending on the above tools, Service development system can realize model customization and timely combat changes of the business. The core of service operating system is JBPM workflow engine. It provides operating environment to the instance of process model and supervise the working instance of process model.Unlike those foregone workflow management systems, the process-based service integration system adopts the service-oriented architecture, build a service integration system and a series of mechanism, such as the service transition mechanism. The transition of process to service is implemented by process binding with API. After binding with API,system will generate the corresponding WSDL file, and then publish it to the Service integration platform. Web service is main implementation techniques for Invocation of the service. Service integration platform is equivalent to a UDDI, the service requester get the WSDL file from it. And then according to the service description file, the service requester use SOAP to invoke API which tied with process.
