Therefore, the idea of using database representation to design and realize workflow came into mind. Based on database representation means that database is the centric and fundamental part of the workflow management system, where not only process definition, process instances are stored in the database, but the workflow engine can be developed directly by using the procedure SQL language as well. The whole thesis is made up of the following five chapters: Chapter one is the preface.It shows the development of the workflow briefly,and this chapter gives the topic of the thesis.It shows the market value of developing the system of visual flow design. Chapter two puts formard the general architecture of workflow.It describes the relationship among the user,the graphics and the database. Chapter three describes the design and realization of the system of visual flow design. Chapter four describes the database representation of workflow. Chapter five is the concluding remark.It gives some ideas of further improvement.
