The term "big data" is trending rapidly across the globe and several businesses as well as authorities have adopted it in their daily activities.  Big Data refers to massive amounts of data that can be on systems, in annual books, in mobile devices, on the internet, and everywhere else. Simply put, big data is a collection of all forms of data in one place.

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.
