Mapping database users to operating system users in a computer schema

This invention relates to databases, database management systems, and database management schemas. Described above is a schema extension of the Common Information Model (CIM), designed to model manageable aspects of a database server such as a Structure Query Language (SQL) server. The database schema contains a view of user-related classes of the operating system schema. These classes are in a different namespace than the database schema. The database schema includes associations between its user-related classes and the user-related classes of the operating system. These associations map database users to operating system users.
