Big Data refers to extremely large and complex sets of information that are too big or too fast for traditional tools to handle. It’s not just about the amount of data, but also about the speed, variety, and complexity.

For example: online shopping, sensors, GPS, and apps create transactions every second, resulting in very large amounts of data. Big Data technologies help businesses store, process, and analyze this flood of data to find useful patterns, make better decisions, or even predict future trends.

It’s called “big” not just because of size, but because of the challenge and opportunity it brings.
