METHOD AND DEVICE FOR MATCHING DATA BETWEEN DATABASES DIFFERENT IN LOGICAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To transfer the unreflected updated record data of an updated source table to an updated destination database after the restoration of the updated destination database to reflect the updated destination database with the data. SOLUTION: Based on an updated flag, a function 26 for batch retransfer extracts all the unreflected updated record data to updated destination tables 14 and 15 from an updated source table 23 of an updated source database 22 and activates a function 25 for data transfer to the respective unreflected updated record data. The function 25 for data transfer performs updating processing for transferring the unreflected updated record data of the updated source table 23 to the updated destination database 12 and reflecting the updated destination tables 14 and 15 with the data and sets an updated flag corresponding to a return value showing the normal end/abnormal end of updating processing to the relevant record of the updated source table 23. A function 13 for table update updates the updated destination tables 14 and 15 based on the updated record data transferred to the updated destination database 21.
