What are the 5 V’s of Big Data?

Big Data is composed of 5 dimensions that characterize it, below I define the 5 V’s of Big Data:

Volume: the volume to be analyzed is massive. Terabytes of information are produced every day, and the capacity of the databases is doubling every two months. To give you an idea, all the data produced in 2 days represents more information than all that generated up to 2003. This makes managing this data a challenge .
Speed: the flow of data is not only massive, it is constant . The great speed of data generation causes them to become out of date quickly. So companies must be skillful, and they have to collect , store and process that information at great speed .
Variety: the origin of the data is very Brother Cell Phone List heterogeneous. From different sources, internal and external, and can come they structured or unstructured, being e l 80% of the data of the unstructured Big Data .

Value: once the data is transformed into information, we must know what value they provide us. The more value the data has, the more performance we will get out of it.
