Research On Implementing Technique Of Enterprise System

The ability to make use of information system and management level of itself are two important foundations to support enterprise's operation. However, the existing implementing technique of enterprise level system has big limitation. Therefore, it can not satisfy the need of enterprise management. This paper uses the workflow as the starting point, then analyzes and summarizes the characters of enterprise level system's need and drawbacks of existing technique at present stage. At last, it prompts a bran-new idea of two aspects; system architecture and plan design analyzing method, and then realizes a Demo system by Java.Enterprise level system is the embodiment of system management's will. Now, under the effect of BPM, KM, ERP and CRM, enterprise has put forward higher requirements to information system implementing technique. They ask the enterprise level system could cope with frequent and structural traffic flow reform, support flow optimization when study and knowledge share, and to be more humanized.Workflow technique has good adaptability to answer the flow change. But from the degree of demonstration, workflow technique has far fallen behind from the expecting result. This paper starts from workflow, analyzes the merit and demerit of existing workflow technique in principle and actual application and then takes these as foundation to prompt the five architecture mode of enterprise level system application, namely, dummy system layer, workflow layer, business rule layer, implementing module layer and database layer. The author uses many spaces to discuss the function of each layer and the relations among the five layers. At the same time, he not only introduces the principle, structure and implementing technique of micro-core workflow engine but also discusses the implementing technique of regular language and regular engine. It also gives plan analyzing design methods of the architecture and points out the importance of question and user action analyzing.Finally, this paper introduces the Demo system designed by the author. This system obeys the five layer architecture and it is a demonstration of the feasibility of the five layer architecture. The paper takes some spaces to introduce and discuss the principle, analyzing method and implementing technique.
