Abstract

PURPOSE:To realize the definition of a virtual data item for a physical file to a record of a logical file, by using a means which produces the virtual data having no correspondence to the physical file based on the generating conditions defined to the logical file. CONSTITUTION:A logical file defining matter 17 is first produced by a logical file defining part 16 based on the logical file definition 14 supplied from a user. In this case, a data item X that designated a generating method in a prescribed form is defines as a virtual data item. While the data item (A.D) contained in a physical file 2, the section showing each item of the virtual data, and the generating method of the virtual data are set the matter 17 for each data item. When a reading request is given to a logical file 12 from a program 19, a logical file access part 18 refers to the matter 17 to give an access to the file 2. Then the item X is produced based on the due definition and delivered to the origin of requesting together with data items A, D.
