摘要

PROBLEM TO BE SOLVED: To provide a work flow processing system for changing a work flow by making it unnecessary for a user to stop this system or to newly change any connection destination as another work flow.

SOLUTION: In response to the execution start request of a work flow, a session managing part 12 assigns session ID for managing the work flow, and manages the work flow name and the session ID and the latest version information of work flow definition information 111 at a point of time when execution start is requested as session management information 13. In response to a session operation request with session ID designated, the session managing part 12 makes an executing part 17 execute an intermediate code 182 generated from the work flow definition information 111 corresponding to the session ID according to the progressing circumstances managed by a context 16 to make the plurality of versions of work flows simultaneously coexist.
