<p>A computer system 1 is provided to assist in the compilation and execution of data models which comprise an inter-linked assembly of pre-defined program components copied from a reference store 7 and stored in a store 3. According to the invention, the computer system 1, including data processing means 2, memory means 4 having a control program stored therein, a store 3 and input and output interfaces, 5 and 6 respectively, is arranged, in operation, to compare fields of program components stored in the store 3 with corresponding fields of pre-defined components stored in the reference store 7 and to identify those fields shown by the comparison to be different. In particular, the computer system 1 is arranged to automatically update a field in the store 3, shown by the comparison to be different, with the contents of the corresponding field in the pre-defined component stored in the reference store 7. <IMAGE></p> |
