In a data-base system including a data-base management system, a dictionary device for managing definition information and generation management information in a data base, and a dictionary file for storing the generation management information, a generation management system is provided between the data-base management system and a data storage file to acquire data in accordance with the generation management information, the dictionary device is made independent of the data-base management system and connected to an input/output device, the dictionary file and the data-base management system, new or update generation management information is registered in the dictionary file by means of the dictionary device when the new or update generation information classified for each item is designated through the input/output device while the timing for acquiring the generation information is designated suitably, and the data-base management system is operated to issue a data-base output request to the generation management system based on the generation management information registered in the dictionary file to thereby make the generation management system read out data from the data base in accordance with the registered generation management information to supply the read-out data to the designated data storage file.
