COMPARISON DEVICE BASED ON DATA DEFINITION INFORMATION

摘要

PURPOSE: To perform the comparison of various user files (data) with a single comparison device by carrying out various types of comparison corresponding to various types of data just by changing the data definition information. ;CONSTITUTION: The information that defines the comparisn items as well as the types of data to be compared is previously stored in a data definition information file DI as the data definition information. Then, the data stored in the files F1 and F2 to be compared with each other and the data definition information corresponding to these data are evolved into a memory, so that the comparison subject file evolution information MF1 and MF2 are obtained. The comparison items are extracted out of the data to be compared with each other and developed in the memory by a comparison item analyzing device base on the data definition information evolved in the memory. Then, the extracted comparison items are compared with each other by a comparison device for each data type of each comparison item.;COPYRIGHT: (C)1995,JPO
