FRAMEWORK SYSTEM

Disclosed is a framework system improved such that flow of complex business logic for processing a variety of messages may be easily defined and changed without need for programming. Messaging service(s) 15 may relay message(s) between client(s) 11, 13 and framework service(s) 16. Among request message(s) relayed from client(s) 11, 13 to framework service(s) 16 there may be message(s) comprising subject ID(s) associated with subject(s) of such message(s). Framework service(s) 16 may possess a plurality of sets of business logic 22 and flow definition file(s) 23. Flow definition file(s) 23 may comprise a plurality of definition sentences respectively corresponding to various subject IDs, and each such definition sentence may indicate schedule(s) for execution of business logic. Framework service(s) 16, upon receiving request message(s) from messaging service(s) 15, may select one or more sets of business logic for execution in accordance with execution schedule(s) corresponding to subject ID(s) of such message(s) indicated in definition file(s). Flow definition file(s) 23 can be rewritten at desired time or times notwithstanding the fact that framework service(s) 16 may be operational at such time(s). In the event that a plurality of sets of business logic are to be executed in linked fashion, framework service(s) 16 may execute subsequent business logic synchronously and/or asynchronously with respect to first business logic pursuant to execution schedule(s) indicated in definition sentence(s).
