Abstract
A distributed data base access request processing system in a distributed data base system including a computer system having a data base and a plurality of computer system effecting an update or a reference to the data base. A client side requesting a data base access issues a request for a synchronous processing to a server side if the data base access is related to a reference operation; whereas an asynchronous processing is requested if the data base access is associated with an update operation. On receiving such a request of a synchronous processing, the server side returns a response to the client side after the requested data base processing is completed. If an asynchronous processing is requested, the response is returned to the client side without waiting for the completion of the requested data base processing.
