METHOD USED IN CLIENT-SERVER DISTRIBUTED SYSTEM, SERVER AND CLIENT

摘要

PROBLEM TO BE SOLVED: To reduce a turnaround time from a time point of a start of server function calling of a client to server processing completion notification, in synchronous communication of a client-server distributed data system. SOLUTION: A server has: a preprocess registration part 101 registering a preprocess; a post-process registration part 102 registering a post-process; a server instruction part 100 requiring the registration of the preprocess and the post-process; and a server function correlation part 103 correlating the preprocess and the post-process to a server function identifier. When the server 10b receives a requirement message for the server function calling from the client, the server 10b executes the preprocess, transmits a completion message including an execution result of the preprocess to the client 10a, and executes the post-process after transmitting the completion message.
