SCADA: as its name Implies Supervisory Control and Data acquisition, is used for monitoring and controlling of Processes which displayed graphically. Through SCADA we can do just small changes during the execution of process ( e.g, we can change only value of variables). Also it gives feature like storing, and can communicate to other servers.
Here programming is done in Scripting language.
