Now-a-days, database system is becoming more crucial as the scale of database is growing. Traditional access control policies have certain disadvantages. So as a promising alternative to traditional access control policy, Role-Based Access Control (RBAC) has received special attention for its unique flexibility. RBAC provides access control based on permissions associated with roles. Among commercial software applications, DBMS provide access control and have applied RBAC.
