What is SCADA ?

SCADA stands for "Supervisory Control And Data Acquisition". It is a computer system which is used for analyzing real time data. These systems are generally used to control & monitor a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation.
A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion.
SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.
