摘要

PROBLEM TO BE SOLVED: To access information at high speed in a case that a primary relevant object is not immediately needed upon the request of an object, but likely to be requested in the following request.;SOLUTION: A server processing program of an O/R mapping server terminal 200 accepts an object acquisition request from a client processing program 11 of an object using client terminal 100, acquires records from a relational database 31, and returns an object to the client processing program 11. In the middle of this processing, an asynchronous cache management program 203 checks an asynchronous message given from the server processing program 201 for whether or not the primary relevant object is present in a cache management device 202, acquires information from the database 31 when it is not present, forms the primary relevant object from the acquisition result, and stores it in the cache management device 202.;COPYRIGHT: (C)2006,JPO&NCIPI
