Method and apparatus for controlling a data access in a data base management system
Software version management system Patent #: 4558413
AbstractThis invention pertains to database management systems and, in particular, to a database management system which has an active data dictionary that the user can both access and modify. The user makes use of simple commands to control, order and query not only the underlying data controlled by the database management system but also the contents of the data dictionary. This capability enables the user to write generic application programs which are logically independent of the data since the subject database management system enables the user/application program to access all data in the database independent of each application program's data model.
