What is meant by the term "big data"?

The term "big data" refers to large volumes of structured and unstructured data that are generated from various sources at high velocity and in different formats. This data can come from numerous sources, including social media, sensors, devices, transactions, and more. It is characterized not just by its size, but also by the challenges it presents in terms of data processing, storage, and analysis. Organizations harness big data to extract meaningful insights, drive decision-making, and enhance operational effectiveness.

This definition encompasses data's complexity and the tools needed to manage and analyze it, differentiating it from smaller, more manageable datasets. The sheer volume, variety, and speed at which this data is produced require advanced analytics and storage solutions that go beyond traditional database capabilities. Thus, "big data" illustrates the shift in how organizations leverage vast amounts of information to gain a competitive edge and innovate.
