What is an Asynchronous Process?
Other names for this are the Background Process, Attendant Process, or Daemon. The classic example is printing. Rather than tying up a foreground process with physically printing a document, the foreground process creates a new background process that handles the logic and I/O for the printer. It is when the application becomes mission-critical and/or more complex that designing a full feature asynchronous process becomes a major undertaking. • Providing prioritized queues for the requests, • providing multiple threads to process the queues and the thread management that goes with it, • providing synchronous access, (wait until complete), and asynchronous access with call-back, • providing automated error recovery, • providing back-out and restart, • providing inquiry and modification to the execution environment. This major design and implementation may cost so much in time and resources that the team looks for easier alternatives. It is for these reasons that there is Tymeac.
