What is Big Data?
Big Data refers to the large volumes of structured, semi-structured, and unstructured data generated by digital processes, social media, sensors, devices, and enterprise applications. It is defined not only by its size but also by the complexity and speed at which it is generated and processed. Big Data leads to insights that support better decisions, innovation, and strategic business actions across industries. The idea of managing and analyzing massive data sets has existed since the early 2000s, when companies began recognizing the value of data beyond traditional structured formats. The term “Big Data” became popular when industry leaders like Doug Laney introduced the 3 V’s model (Volume, Velocity, and Variety). At first, traditional RDBMS systems had trouble with the complexity, and new frameworks like Hadoop emerged to store and process data at scale. Over the years, Big Data changed from a niche capability to an essential function for businesses of all sizes, leading to the creation of better analytics tools and scalable storage platforms.
