Enterprise workflows change dynamically and many kinds of people are involved in the flow of work, We get the idea of wok-flow engine to deal all the work, which is a System based on the idea of OA(Office Automation).This research has covered the design and realize method of workflow engine, and finally we put this engine into reality. This realization of this system has positive effect in solving the problems of work configure, cooperation, privilege set, est.This topic is practice-oriented. It analyses latest work-flow engine realization method, and the possibility of get a work-flow engine based on the technology of XSQL and AJAX, which now becomes the most popular web application develop language.We make our idea clear, and the plan sounds possible. From the view of easy to use, require low level web container, no enterprise environment required, we make out a possible plan and realized the problems we will face in the future.This topic is based on a real enterprise business requirement, which is raised after a deep research on the possibility of realize a work-flow engine with the XSQL and AJAX technology. As XSQL haven't supplied enough security mechanism, so we write many actions to overcome the short comes of XSQL .These actions check the session to found the user's permissions and privileges, and solved the security and privileges auth problems perfectly.
