Big Data can be describes as having the '3 Vs'.
Volume: (amount) this refers to the amount of information which is collected by people. There is a very large number of people data is being analysed from. For example Facebook has over 2 billion users it collects and processes vast amounts of data from. By analysing and sorting all of this data Facebook has information about patterns and trends in human behaviour.
Velocity: (real time , batch) The data passed is in real time meaning that as soon as a person does something online it is instantly processed. The data has to be processed very quickly due to the volume of data constantly being generated.
Variation: (structured, non structured) Structured data is made up of clearly defined data types meaning the data can be put into categories and can be easily searched as it in an organised format. Non structured data on the other hand is data which is in a format which makes it hard to organise the information, for example videos or Facebook posts are hard to find what data can be taken from it.
