In a nutshell, big data is a larger, more complex set of data, especially from a new data source, and yet the new sources of data are growing exponentially with time. These data sets are so large that traditional data-processing system cannot store, process and manage them efficiently. But this massive amount of data can be used to solve previously unsolvable business problems.
There are many different use cases of big data, for examples:
- Discovering buying patterns for customers.
- Personalized advertising and relevant product recommendations
- Personal preferences for content suggestions for a search engine
- Health conditions tracking through data from wearables.
- Live mapping of roads for autonomous vehicles.
- Predictive ordering of inventories.
