Research On Web-based Workflow Management System

The concept of workflow is put forward for improving work efficiency in enterprise management. Through electronic communication and network technology, it makes the process of execution of concurrent assignment in enterprise be linear. It relate to several domains such as mechanism, management, information, science of computer and so on. And it is applied in many aspects such as electronic commerce, product design, remote education, etc. Now, web-based workflow management system has become the focus of research and advanced domain in workflow management systemThis paper introduces origin and development of workflow, gives definition of workflow based on describing workflow conception from various views. The author classifies workflow management and discusses the problem and hotspot of workflow system based on analyzing concluding typical workflow system product With expounding the basic concept of workflow and correlative relationship, workflow reference model, this paper gives idiographic workflow system framework. Through analyzing and comparing, web-based workflow management system is modeled with object-oriented modeling technology.This paper expounds key technologies such as ORB(Object Request Broker), IDL(Interface Definition Language), OA(Object Adapter), IDL stub, IDL skeleton, DII(Dynamic Invocation Interface), DSI(Dynamic Steleton Interface) of CORBA technology system framework and HTTP protocol, script language programming, web object computer system and web security technology of web technology. The author researches the application of these technologies in web-based workflow management system.This paper describes in detail the realization of web-based workflow management system with three layers B/S/D configuration and Object-Oriented technology. It describes the system's realization environment and framework, describes database configuration in the system, expounds the design of process define tool and management control tool.Finally, the paper is summarized. According to the development of workflowtechnology at present, this paper forecasts the development of workflow technology in the future.
