ABSTRACT:
A database management system that supports multiple databases in an instance with controlled sharing between the databases. The invention can also support execution of procedures and other modules in the context of any principal possibly different from that of the caller. Trusted certificates can be employed to permit access to procedures (or other modules). The security context of the invention can enable the building blocks of building a pure trusted sub-system model of authorization.
