CLIENT-SERVER SYSTEM AND METHOD FOR REDUCING LOAD FOR REFERRING TO MASTER

摘要

PROBLEM TO BE SOLVED: To provide a client-server system and a master reference load reducing method capable of referring to a master at a response equivalent to a LAN environment by using absolute minimum hardware without being conscious of master management even in a wide area network(WAN) environment. SOLUTION: The client-server system is provided with a client side system 20 provided with a function for checking the number of versions of each master 18 and a server side system 10 for generating an extraction file 14 (extraction F) by extracting the master data of the master 18 simultaneously with the management of the number of versions at the time of updating the master 18 and transferring the already extracted extraction file 14 when the system 20 fetches data.
