Design And Implementtation Of Medical Examination System Based On Workflow

With the widely usage of the computer and the development of Internet technology, the traditional working mode and workflow is applied and is further improved by computer, the software upgrade is much cheaper than the personnel readjustment.Based on this background, the workflow technology is widely applied in industrial, office and manufacturing environment. More and more companies need to follow the highly development of the society, they have an urgent requirement of a highly extensible and more flexible computer product. However, the traditional upgrade process of software development is quite complex, with the long duration from software modify to the final release, it is difficult to satisfy the demands. On the other hand, some important technologies are highly improved and developed, for example, the Internet development increases the development of information communication technology and the cooperative working mode; the information release and process method based on the browser can simplify the definition of information process and the final release; the newly Web development architecture make the web develop process more efficient and flexible, and also can afford huge number of users; the development of Web server is quite stabile and secure; the traditional software products can be transplanted into Web. So for some applications which have less complexity of data computation but more processes, the develop method based on B/S architecture is the first choice.In this paper, the basic knowledge of workflow technology and the categories of workflow engine are introduced first, the concept of J2EE technology and development model are addressed then. The method of applying workflow and SSH architecture into the development of medical examination system is researched, and the advantages and problems of using this architecture are presented. The details of the system development, including the function model, the database designation and the special system interfaces for certain functions are introduced after solving the above problems.The develop process is introduced at the end of this thesis, from the beginning process of user registering personal information, examination payment. medical examination, to the final process of informing the examination result and granting the certificate. The details of design the system is explained based on the principle of workflow technology. By using workflow technology during the development of the examination system, the specific functions are achieved perfectly. On the other hand, the usage of Hierarchical design technology in SSH architecture makes the system more flexible.
