Abstract
The database system includes a definition data file to store definition data for the storage units established in the database file, and loads the definition data from such definition data file to the definition data storage section, refers to the loaded definition data, and opens, updates/retrieves and closes the database file. A re-loading judgment section judges whether or not the definition data for the storage units have been changed after loading definition data to the definition data storage section and before opening of the data base file and, if the definition data have been changed, directs re-loading of the definition data.
