For those who are new to the concept of SCADA, they need to know that it is the acronym for Supervisory Control and Data Acquisition. Before it used to be a concept that referred to the way data is managed and procured in process management systems. That is a broad definition of this system as this term is used in varying instances these days. As per the location, the term can have different meanings. For instance, in the case of North America, it usually refers to a distributed measuring and management system that is used across a wide base or area. For other areas across the world, the meaning of the term is similar, though it is used in different environments as well as in different scales.

For any free SCADA process the essential components are that of data collection and control. Not only does the data have to be acquired, but it also needs to be managed in different contexts. The supervisory aspect of these systems is meaningful which means that a centralized point of data collection, measurement, and management is critical or an identifying feature of these systems.

There are different kinds of SCADA free software systems that are developed in order to allow any organization or venture to collect data, measure the same and make sense of it through the application. When a SCADA system is soundly built, it makes the whole process easy and seamless. Data can be retrieved easily and quickly as well as complied and analyzed with the same system. Many places make use of SCADA systems which are marketing, quality control, development of sales brochures, market research and other areas. Nowadays, many application developers offer generic SCADA systems which can be customized to meet the needs of the different clients. Others often opt for free software to put to use in their initiatives.
