PURPOSE:To facilitate generation of an application program which accesses a data base, by storing information of the data structure related to the data base and information of the processing process of the application program to the data base. CONSTITUTION:The data structure of a constituting element or the like of a data base 1-2 is stored in a data structure storage part 1-4, and records or the like processed by an application program 1-1 till then are stored in a processing process storage part 1-42. A data structure retrieving part 1-52 retrieves a storage part 1-41 on the basis of request information from a request data input means 1-3 by the function of a flat access control part 1-51 and reads out information of the data structure of the base 1-2 related to request information. A processing process storage retrieving part 1-53 checks contents of the storage part 1-42 and reads out information of the processing process executed till then of the base 1-2 related to request information. Thus, the control part 1-51 assembles a series of instruction execution procedures by which the data base can be accessed.
