The document examines the specific functionality that might be required of relational database management systems (DBMS's), and compares them with the requirements and options of the SQL specifications. The comparison shows that the security functionality of an SQL-compliant DBMS may vary greatly. A variety of security policies are considered which can be supported by SQL. The document ends by showing which types of functions are required by the examined security policies.
