ABSTRACT:
A computing system for a data processing apparatus which carries out data processing using a formula. The system includes a link data file for storing formulas which are described by command names assigned to data elements and operation symbols which define operation between the command names, an actual data file for storing actual data in correspondence with the command names in the formulas managed by the link data file, and a computing file for operation processes for computing the operation contents of the operation symbols in the formulas managed by the link data file. A process is provided for specifying a requested formula which is to be computed by referring to the link data file in response to a computation request, reading from the actual data file the actual data corresponding to the command names in the specified formula and reading from the computing file the operation processes corresponding to the operation symbols in the specified formula, and carrying out operations of the operation processes read from the computing file with respect to the actual data read from the actual data file.
