Then, the modified query is executed and the results returned to the user. VPD functions may exploit application contexts. An application context stores a set of properties of users/sessions that may be used by VPD policies to enforce context-based access control constraints. Application contexts may be system or user defined. ). Attributes of the USERENV context cannot be modified. If one wants to specify a policy exploiting additional attributes with respect to those contained into USERENV, he/she can create his/her own contexts, through the CREATE CONTEXT command.
If a VPD column-level policy is specified for a column C of a relation R, then, when C is referenced in a query, the system returns by default only the rows of R that satisfy the policy. Columns that trigger the evaluation of the policy can be specified by using the sec_relevant_cols parameter of the ADD_POLICY procedure. 4 and suppose that the following policy should be enforced over it: each user can see all the information in the Rentals relation, apart from information 5 We refer the interested readers to Oracle Corporation  for the whole list of parameters that can be used in the ADD_POLICY procedure.
Such modeling concepts need to be taken into account when developing an access control model. For instance, the semantic relationships existing in the object model can be exploited to establish relationships between the authorizations given on semantically related objects. The other key difference between the object model and the relational one is that an object, besides being a data container, can have methods associated with it. Therefore, method invocation and their accesses to the managed data should be properly regulated.
