Research The Theory And The Application Of Three-layer OA System Based On Workflow Technology

In recent years, the workflow technology develops rapidly. and applies especially in the OA computer,integrating manufacture system,and e-business etc. The workflow technology derives from OA, and applied in many other areas, along with the development of times .At the background of network and co-operation technology, raditonal OA adopted two-layer architectures and non-relation database,but with the revovation of technology,this model represents much limitation.This paper introduce the status inquo,the study meaning and the concepts of workflow technology,analyse the architecture of J2EE,research the MVC mode.On base of the OA system of ANSHAN power supply company,the thesis discuss the realization of workflow technology based upon three-layer B/S architecture, In the system,it adopts the MVC pattern, J2EE architecture, relation database. As company standard operational basal information technology platform, this OA system provide a support for handling official business and running of operation of the company.
