SCHEMA INTEGRATION SUPPORT DEVICE, SCHEMA INTEGRATION SUPPORT METHOD, AND SCHEMA INTEGRATION SUPPORT PROGRAM

摘要

PROBLEM TO BE SOLVED: To prepare mapping information of a table without using "domain information" and an "attribute name", in integration processing of two databases.;SOLUTION: A schema information extracting part 103 acquires schema information indicating data structure of the table, from the first database 100 and the second database 101 to be integrated, to be stored in a schema information storage device 104. A feature information generating part 105 calculates the number of respective data items constituting the each table, based on the scheme information, in every kind of defined attributes, to be stored in a feature information storage device 107 as feature information, in the each table. A similarity evaluating part 108 compares the feature information in the table of the first database 100 with the feature information in the table of the second database 101, and calculate similarity, to be stored in a mapping model storage device 110 as the mapping information, while correlating the compared tables with the similarity thereof.;COPYRIGHT: (C)2007,JPO&INPIT
