PURPOSE:To uniform a tuple in a data base by preparing a table for managing plural tables for attaining a data base and providing each table with tuple ID modifying the ID of table information. CONSTITUTION:The table managing table 3 stores the information (table names, etc.) of respective tables of a schema managing data base 1 and an employee data base 2 and the ID of each table to be managed is modified by each tuple ID of an ID (identification information) part. Namely the ID of a corresponding table is set up on the decimal pat of each tuple ID in the table 3. The integer part of the tuple ID becomes a table identifying ID and coincides with the ID of the decimal part of the table 3. On the other hand, the decimal par of the tuple ID 4 indicates the tuple in an objective table. Since the tuple in the data base is unified, a table and its tuple can be identified only by reference information.
