Abstract: An data processing method includes: determining, from execution-target data, a plurality of data items included in the execution-target data, a same series of a plurality of processes being executed for the plurality of data items; associating identification information with each of the plurality of data items; and executing batch processing of the plurality of data items with which the identification information has been associated.

Abstract: A device includes a memory configured to store a program; and a processor coupled to the memory and configured to execute a process based on the program. The process includes: for input data made of a combination of pieces of unit data and including a plurality of consecutive records each including data of a plurality of items, when a sequence of type information indicating a kind of each piece of the unit data in the input data is divided into partial sequences each having a certain length, analyzing a break position of the records in the input data by determining, as a length of each of the records, the length of each of the partial sequences when sequences of type information in all the partial sequences correspond to each other.

Abstract: Disclosed is a method for designing an electrode for electric discharge machining of a workpiece, based on a reverse shape to a shape of the workpiece by use of a CAD system, which comprises the steps of obtaining a first reverse solid having a reverse shape to a shape of the workpiece, from a solid of the workpiece, uniformly offsetting an entire surface of the first reverse solid by a thickness necessary for a discharge gap to obtain a second reverse solid and subjecting the second reverse solid and one or more swept reverse solids created by copying the second reverse solid while allowing a sweep movement by a small distance in a direction conforming to a rocking motion, to a logical product (AND) operation to obtain a shape of an electrode as a third reverse solid.
