In this paper, we study for the theory of component technology and the workflow technology and method of component composition of component and component library, based on the principle of workflow technology and the component composition technology, the method to study and put forward the component assembly based on workflow technology system structure. Using this method to separate business process logic and business process implementation, under the condition of without modifying the specific function component, by redefining process model to accomplish system function change or improvement of system performance, make the enterprise can according to the business process dynamically build enterprise information system, changed the enterprise's business and process to adapt to the traditional software development model.

This paper first introduces the basic concept of UML and artifacts, then discuss the UML and artifacts in the important role of information systems development, and combined with the development of information system of UML and components of feasibility analysis are studied, finally combined component model with UML modeling technology to develop information system has carried on the systematic study, based on UML is proposed and the components of information system development process.

This paper first discusses the related concepts of software component technology based on software component technology and software development method, and then based on the UML technology component extraction method and component extraction strategy, the system, the component extraction, the establishment of system function of each part and component model, software component technology is introduced into the online test system development, so as to improve the application software system development speed and efficiency and maintainability, reconfigurability and scalability.
