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. But RBAC have also certain inherent weaknesses. So in this paper the authors enhance the RBAC policy named as Level Wise Role-Based Access Control (LWRBAC) policy that is instead of access control through role assigned to the users.
