First, let’s start with the definition of big data. Big data means large sets of structured and unstructured data. It is so large and complex that regular data processing techniques do not work in dealing with this type of data sets. Generally, in the industry, the 3V model is used to describe big data. These 3Vs are; volume, velocity and variety.
Volume is related with how the data is stored. Businesses collect data from many sources such as sales transactions and social media and storing this continuous data was a problem in the past. Nowadays, big data technologies made storing data easier. Velocity stands for real time data. Data streamed in real time must be dealt with immediately. Finally, variety refers to the different formats of data such as text, video, image and audio. Businesses should be able to arrange and store data in all formats.
