【Abstract】 The increasing popularity of database desires guarantee of their security acutely.But secure database application system development is an expensive and time-consuming task.It is well known that Software Engineering and CASE(Computer Aided Software Engineering)are considered as powerful approach to ease this problem by providing a toolkit for specific issues in software developing.Applying the software engineering methodology to the secure database system development will simplify the developing process.The paper tries to combine the security control mechanism and database developing technique by applying software engineering method on the basis of Entity-Relation model(ER model)to construct a Security Extended ER model.A CASE toolkit prototype DBST based on the SEER model is illustrated at the last part.The research of SEER model and the development of DBSDT puts forward a new ideal about database security.更多还原
