Abstract
Abstract A computing system for a data processing apparatus which carries out a data processing using at least a formula includes a link data file (11) for managing formulas which are described by command names assigned to data elements and operation symbols which define operation contents between the command names, an actual data file (12) for managing actual data in correspondence with the command names in the formulas managed by the link data file, a computing file (13) for managing computing means (131) for computing the operation contents of the operation symbols in the formulas managed by the link data file, and a processing part (15, 20) 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 computing means corresponding to the operation symbols in the specified formula, and carrying out operations of the computing means read from the computing file with respect to the actual data read from the actual data file.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
A computing system for a data processing apparatus which carries out a data processing using at least a formula, characterized in that there are provided: a link data file (11) for managing formulas which are described by command names assigned to data elements and operation symbols which define operation contents between the command names; an actual data file (12) for managing actual data in correspondence with the command names in the formulas managed by said link data file; a computing file (13) for managing computing means (131) for computing the operation contents of the operation symbols in the formulas managed by said link data file; and a processing part (15, 20) coupled to said link data file, said actual data file and said computing file and including first means for specifying a requested formula which is to be computed by referring to said link data file in response to a computation request, second means for reading from said actual data file the actual data corresponding to the command names in the specified formula and reading from said computing file the computing means corresponding the the operation symbols in the specified formula, and third means for carrying out operations of the computing means read from said computing file with respect to the actual data read from said actual data file.
Claim 2
Dependent Claim
219 words
A computing system for a data processing apparatus which carries out a data processing using at least a formula, characterized in that there are provided: a link data file (11) for managing formulas which are described by command names assigned to data elements and operation symbols which define operation contents between the command names; an actual data file (12) for managing actual data in correspondence with the command names in the formulas managed by said link data file; a computing file (13) for managing computing means (131) for computing the operation contents of the operation symbols in the formulas managed by said link data file; and a processing part (15, 20) coupled to said link data file, said actual data file and said computing file and including first means for specifying a requested formula which is to be computed by referring to said link data file in response to a computation request, second means for reading from said actual data file the actual data corresponding to the command names in the specified formula and reading from said computing file the computing means corresponding the the operation symbols in the specified formula, and third means for carrying out operations of the computing means read from said computing file with respect to the actual data read from said actual data file.
Claim 3
Dependent Claim
104 words
The computing system as claimed in claim 1, characterized in that there is further provided a parts file (14) coupled to said processing part (15, 20) for managing first attribute information of the formulas managed by said link data file (11) and second attribute information of the actual data managed by said actual data file (12) using predetermined names respectively assigned to the first and second attribute information for easy user identification, said first attribute information including at least the command names managed by said link data file, said second attribute information including at least the command names managed by said actual data file.
Claim 4
Dependent Claim
21 words
The computing system as claimed in claim 2, characterized in that said computation request is made via said parts file (14).
Claim 5
Dependent Claim
