The Query Management System on Student Performance
Abstract
Develop the student performance query management system, improve the efficiency of management of the score, facilitate students and teachers use, near promoting educational administration mechanography, modernization, informationization educational administration in school test affair work extremely important. The article introduces the process of developing student performance query management system of Information and Technology College. And it is exhaustively elaborated the whole developing process from demand analysis, system logic solutions, system design overallly, detailed design, and also some partial methods of the software engineering.
What was expounded the fact is a development process based on the management information system of B/S structure in the article, the demand is analysed stage uses the organization structure chart and opertional flow chart to analyse carry out the demands of users. The design of the logic scheme of the system uses the data flow chart and data dictionary to do logic design to the system. The system is overall to design and use the tools, such as HIPO picture, etc.Since the use of the database is available, it explain some to only list the relation of the database in the database is analysed. Development process from the whole system of description as detailed as possible in the article. The application that can be developed as the similar computer management information system is consulted.
The system function modules is clear, it is compact to join. It is capable of completes the data gather, query and calculation automatically. Not only increases work efficiency, but also increases quantity, guaranteed the accuracy, validity and reliablity of the data.In addition, according to the demand it can proceed the query and manage at any time to carry out online, reflected the students score information accurately on time.
The system adopts JSP development instrument and Tomcat server and mature software to research and develop technology during the process of developing. Massive work has been done in some more sensitive JSP questions, which will be elaborated this paper.
