The difference between big data and traditional data storage

The main difference is that big data now includes unstructured data, from which useful information can be extracted, such as e-mail, log files, social multimedia, business transactions and other data. For example, the sales chart data of goods in chain retail stores stored in the database. The acquisition of these data is not a problem in the category of big data. One of the main characteristics of big data applications is real-time or near real-time. Big data needs infrastructure equipment with extremely high performance, high throughput and large capacity more than traditional data storage.
