During the university, computation the synthetical evaluation is necessary per term. The manual computation of synthetical evaluation is a much numerous and diverse process. First, everyone compute the scores by themselves, and make a draft, then deliver it. Second, the cadres in the class check the result and import the data into computer for making the document, then hand in it to a relative department or academy. In the process, the students are sick of it. Therefore, the veracity of the draft is low. On the other hand, manual checking and scores’ inputting cause the greater workload and lower efficiency. Moreover the veracity is unable to be guaranteed. So, all the teachers and students are looking forward to have an informationizational system of the synthetical evaluation. Using the system, students can’t only compute their scores of synthetical evaluation conveniently and correctly, but also can submit the results to the server. Which can omit the complicated work of class cadres’ manual checking and scores’ inputting. Moreover, the function of query offered by the systems can make convenient for students to search the information they want.The discourse introduces the Applet technology, the analysis and design of the system, the implement of every function module, the test and debug of the system, and the problems met in the exploitation as well as the solution to them.
