Data processing system having a plurality of units in which design of the system can be changed by simple definition

Claim 2

A data processing system for processing data by a plurality of data processing units, comprising: a plurality of data files; a plurality of unit means arranged in one-to-one correspondence with said plurality of data files, each for processing, in response to a predetermined processing command, individually a plurality of types of data stored in a corresponding one of said plurality of data files; a plurality of table means, arranged in one-to-one correspondence with each of said plurality of unit means, for storing identification names corresponding to whichever of said plurality of unit means the one of said unit means corresponding to a particular one of said table means is to be connected; and one of said unit means including means for: storing data transferred from another one of said plurality of unit means into the data file corresponding to said one unit means, processing individually each type of data selected by an operator from among the plurality of types of data stored in one of said plurality of data files corresponding to said one unit means, determining whether or not any of said identification names is stored in the table means corresponding to said one unit means, transferring the individually processed types of data to each of the plurality of unit means corresponding to the plurality of identification names that are determined to be stored in the table means corresponding to said one unit means, and deleting the selected data from the data file corresponding to said one unit means after the transfer is completed.

Claim 3

A data processing method in a data processing system having a plurality of units, comprising the steps of: executing a first process with a first unit with respect to each data selected by an operator from among a plurality of data stored in a first file arranged in correspondence with the first unit to thereby generate first data, with a first identification name being associated with said first unit; referring, by means of the first unit, to a second identification name and a third identification name stored in a first connection table arranged in correspondence with the first unit; transferring, by means of the first unit, the generated first data to a second file designated by the second identification name and a third file designated by the third identification name; deleting, by means of the first unit, the selected data from the first file after the first data is transferred to the second and third files; executing a second process with a second unit with respect to the first data transferred and stored in the second file to thereby generate second data; executing a third process with a third unit with respect to the first data transferred and stored in the third file to thereby generate third data; referring, by means of the second unit, to a fourth identification name stored in a second connection table arranged in correspondence with the second unit; transferring, by means of the second unit, the generated second data to a fourth file designated by the fourth identification name; and executing a fourth process with a fourth unit with respect to the second data transferred and stored in the fourth file to thereby generate fourth data.

Claim 4

A data processing method in a data processing system having a plurality of units, comprising the steps of: executing a first process with a first unit with respect to each data selected by an operator from among a plurality of data stored in a first file arranged in correspondence with the first unit to thereby generate first data, with a first identification name being associated with said first unit; referring, by means of the first unit, to a second identification name and a third identification name stored in a first connection table arranged in correspondence with the first unit; transferring, by means of the first unit, the generated first data to a second file designated by the second identification name and a third file designated by the third identification name; deleting, by means of the first unit, the selected data from the first file after the first data is transferred to the second and third files; executing a second process with a second unit with respect to the first data transferred and stored in the second file to thereby generate second data; executing a third process with a third unit with respect to the first data transferred and stored in the third file to thereby generate third data; referring, by means of the second unit, to a fourth identification name stored in a second connection table arranged in correspondence with the second unit; transferring, by means of the second unit, the generated second data to a fourth file designated by the fourth identification name; and executing a fourth process with a fourth unit with respect to the second data transferred and stored in the fourth file to thereby generate fourth data.
