Abstract: The invention relates to a method of processing requests for the transfer of data from a first data base (40) to a second data base (50) comprising the steps of creating a communications link between the two data bases, and initially transferring from the first data base to the second data base information about the data to be transferred, determining in the second data base the characteristics of the information, and subsequently transferring the required data if the characteristics of the information satisfy predetermined requirements. According to the invention the method is characterised in that the transferred information comprises a description (44) of the data formats used in the first data base, and a description (45) of the data base language used in the first data base. The invention also relates to apparatus for implementing the above method.

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.
