This massive amount of acquired big data can be in any format, such as:

Data that is well organised and can be obtained using simple queries. Database, data warehouse, ER, and CRM are some examples. This category includes data types with a predetermined structure.
- Volume signifies the quantity of the data
- Velocity denotes the pace at which data is created
