ABSTRACT:
The present invention is for increasing operational speed for appending or updating data in a remote database system of the client-server type. When an operational unit of a client node accesses a record file in a server node, and when an attribute associated with an item to be accessed is the likely source of error on accessing, to an output command to the record file in the server node, synchronous operation is performed where the client node waits for notification of an output completion result from the server node and then proceeds to the subsequent transactions. On the other hand, asynchronous operation is performed, when there is no possibility of error, where the client node proceeds to the subsequent transactions without waiting for notification of an output completion result from the server node.
