SYSTEM GENERATING SYSTEM

PURPOSE:To maintain the reliability of a new system at a high level by shortening a term from the development completion of new resources to operation start. CONSTITUTION:A relational expression expressing the designation rules and mutual relation rules of respective operands at a definition information parameter to be inputted at the system generation time of a computer system is normalized and stored in a check information data base 22. A sub program group 24 is prepared for checking the operands in the definition information parameter 21 based on this relational expression. A processing program 23 to be a base at the time of system generation execution decomposes the inputted definition information parameter 21 for the unit of the operand, performs various checks by calling sub programs 241-247 and performs the output processing of a definition information data set 26 and an executed result list 27 when no error is generated.
