What is Big Data?

Big data refers to data sets that surpass the processing capabilities of traditional database systems due to their immense size, rapid movement, or lack of conformity to the structural requirements of conventional database architectures.


When you’re talking about regular data, you’re likely to hear the words kilobyte or gigabyte used — 10^3 and 10^9 bytes, respectively. In contrast, when you’re talking about big data, words like terabyte and petabyte are thrown around — 10^(12) and 10^(15) bytes, respectively. A byte is an 8-bit unit of data.

What are the four V's of Big Data?

Big data is characterized by four main aspects, known as the four Vs: volume, velocity, variety, and value. As these attributes of big data are constantly expanding, there is a continuous need for newer and more innovative technologies to address big data challenges. When uncertain, apply the 4V criteria to distinguish between big-data and regular-data issues.
