Abstract: The present invention relates to a data base system comprising a first computer (10) which is used to execute an application program (14), a data base (56) containing selected data for use in connection with the application program, a second computer (12) which is used to control the part of the data base system which contains the data base, the first and second computers being different types, means 17) for extracting from the application program data base commands which can be executed on the second computer but cannot be executed on the first computer, and means for replacing the extracted data base commands with call commands and for using the call commands to initiate the execution of the data base commands when required. According to the invention the data base system is characterised in that it also comprises means (46, 50) for transmitting the data base commands to the second computer, and means (52) for utilising the call commands in the application program to initiate the execution of the data base commands by the second computer on the selected data in the data base.
