Data is everywhere. Each incident, conversation or transaction can be regarded as data. It is just virtually anything that happens in the world.  Big Data refers to the process of collecting such data and storing it in a single archive or infrastructure.  It can be large datasets or even strategies and technologies that are used to handle such large data sets. Yet such massive amounts of data can be of value, only if they are analyzed and if insights are generated from them. This is the general meaning of big data analytics.
