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.
