06, it is not possible to directly access the database in the intranet of the group, but by accessing the database synchronized with the database in the intranet, that is, the database k109, it is possible to obtain the same information as accessing the database in the intranet. .

Alternatively, a user who accesses the database k109 by using the mobile phone 110 can access the database k109.
When the data in 109 is rewritten, the database a 107 in the intranet and the database in the group site b (not shown) are updated by the synchronization means. Therefore, even when going out, the data is rewritten using the terminal in the intranet. Can do the same as

Next, the synchronization between the database in the intranet and the database outside the intranet will be described. FIG. 2 is a diagram showing synchronization when the database a107 in the intranet is rewritten by a terminal or the like (not shown) in the intranet. Here, a program for monitoring data writing is resident in the intra-server 105. When the data rewrite is detected, the difference data generated by the rewrite is transmitted to the Internet server 108 via the http protocol. The Internet server 108 updates the database k109 using the received difference data. Here, the communication by the http protocol is permitted by the setting of the firewall.

FIG. 3 is a diagram showing synchronization when the database k109 outside the intranet is rewritten by a mobile phone (not shown). This is the step of synchronizing the updates of the intranet external database with the databases in the intranet. Here, a program for monitoring data writing is resident in the Internet server 108. An http request is sent periodically, and the difference data generated by rewriting via the http protocol is transferred to the server 1 in the intranet.
