Abstract :
The paper analyzed from the existing security problems of the traditional coarse granularity to database access mechanism, introduced the necessity of fine granularity access control mechanism into the development process of WEB technology, also described the Oracle Virtual Private Database (VPD) access control policy based on predicate method, and gave the performance optimization methods of data access under this policy.
