What is Big Data?
A primer for students who are new to the big data revolution.
Big data is used to describe a vast quantity of data that is so large that it becomes too difficult to manage using traditional technologies.
Big data is often defined using the three Vs:
- Volume: The vast amount of data available, which leads to storage and management issues.
- Velocity: How fast data is being produced and aggregated and how fast the data must be processed to meet demand.
- Variety: The number of types and sources of data, which can be structured and unstructured and can come from virtually anywhere. 1
Data analytics makes it possible to extract the fourth V: Value.
How Big is Big Data?
1.8 zetabytes of information are created globally in a year, and that amount is expected to double every year. This volume of data is the equivalent of 200 billion two-hour HD movies, which would take one person 47 million years to watch. 2

Why is Big Data Important?
Great strides have been made in the gathering, storage and security of big data, but the real opportunity is in the data analysis.
Its application is virtually limitless, and will shape the world we live in—from the way we interact on a personal level to how businesses and governments evolve.
The increased use of big data in virtually every sector has created a talent gap for data analysts.
