  • Patent number: 5751949
    Abstract: A security system and method are provided for securing user access to server tables having data arranged in rows and columns. The server table is contained in a server computer which is accessible by a plurality of user terminals joined thereto. The server computer includes relational database software for creating and maintaining tables, including the server table, and views defining subsets of the tables. A security table is stored in the computer for identifying authorized user access to preselected rows of the server table for pre-identified users. An access view is stored in the computer for automatically joining the security and server tables to limit user access to the server table to the preselected rows thereof based on the security table. A single security table may therefore be used and is readily updated by merely deleting, adding, or updating entries.
