<p>A messaging service (15) relays request messages including a subject ID from clients (11, 13) to a framework service (16). The framework service (16) has business logics (22) and flow definition files (23). Each flow definition file (23) contains definition sentences corresponding to various subject IDs. Each sentence describes an execution schedule of a business logic. The framework service (16), according the execution schedule corresponding to the subject ID of a received message, selects one or more business logics and executes them. The flow definition files (23) can be updated at any desired time even in operation. If some of the business logics are cooperatively executed, a business logic succeeding the preceding business logic can be executed synchronously or asynchronously depending on the description of the flow definition file.</p> |
