Abstract: The present invention extends to methods, systems, and computer program products for a declarative model security pattern for use in a database. Declarative language code can include a declared access control predicate and a separately declared data structure definition bound to the access control predicate. A portion of the database is instantiated from the declarative language code. The instantiated portion of the database includes one or more tables and a view of the one or more tables. A database management system enforces the access control predicate by dynamically calculating a value for the access control predicate and using the dynamically calculated value to define what operations may be performed on data in the one or more tables via the view.
