SQL-based educational management system design

In today´s rapid development of computer network technology, in order to continuously improve the efficiency of the educational management work, construction of an educational management information system which is based on B/S structure and not subject to time and space constraints has become an inevitable trend. This paper applies the database into the educational management information system and gives a static model of the system through analysis of the relationship between the system class and class. Using sequence diagrams and state diagrams to in detail analyze the system´s main cases, and then give the system dynamic model. Subsequently it also has specific design of the system architecture and database, and gives the system implementation process.
