DATABASE ACCESS SYSTEM AND METHOD, DATABASE ACCESS SERVER, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide access to a plurality of databases having different interfaces by means of a single interface without losing data integrity with an existing system. SOLUTION: A service container part 230 of a DB access server 200 that receives a request for a data operation from a client 100-1 starts a DB access service providing part 240-1 that provides the requested data operation. A DB controller 260, as instructed by the DB access service providing part 240-1, selects a DB 300-1 managing the data to be operated, and uses an interface mounted on the DB 300-1 to command the data operation and receive data operation results. A template management part 250 maps the data operation results according to an output template read out from a template 252. A Web access part 210 returns the mapped data operation result to the client 100-1. COPYRIGHT: (C)2005,JPO&NCIPI
