Big Data shares the same definition as that of data, with the only difference that it is huge in size. Big Data is not only massive, but it also has the potential to grow exponentially for an indefinite period. It can grow even to the extent where it cannot be managed or processed by using traditional techniques such as RDBMSs.

There is no benchmark concerning size to determine whether the given data is big data or not. One of the definitions for big data is —

If the data has expanded to such an extent that now a single computing system is unable to store and process it, then we can call this data, big data.

Today, access to the internet has become affordable, and Internet usage has grown widespread. Each online activity, such as sending emails, booking movie tickets, posting on blogs, posting reviews on an e-commerce portal, etc., generates massive volumes of data. This growing use of the Internet facilitates data generation and easy access to the generated data. Hence, we have entered a world that has become data-driven. Organisations and various industries are leveraging the power of big data to make important decisions.

Following are some important aspects of big data. This is very similar to the 4Vs associated with big data which we will cover later.
