Abstract: A system and method for controlling access to components in a database is provided. The system and method provides flexible access control with variable granularity using a generalized mapping model (GMM) transform of data from one or more databases into a plurality of GMM objects, and mapping the GMM objects to access control settings using an access control mapping. The database access control system and method uses the structures of objects created by the GMM transform to identify and facilitate selective access control to any part or combination of components in the database, including the data and implicit relationships among data. The system and method facilitates individual control of the security permissions and conditions for the components using one or more access control maps to define which data components and relationships different access control procedures are applied.

Abstract: A method and apparatus for reconstructing a database structure. A database structure having a domain structure is provided as is data and the database structure then reconstructed into a transformed database structure by generating a plurality of structures. The plurality of structures include structures generated as a function of the domain structure and structures generated as a function of the data.
