Big data is not about the size of the data, it’s about the value within the data. In computing terms, it refer to the extremely large sets of data that could be used to analyze the trends and patterns of a particular behavior. In a study, Gartner says “It’s not just about Big Data; it’s what you do with it.”
4 V’s of Big Data:
Volume: Volume defines the amount of data generated and stored. It contains enormous quantities of data that can range from terabytes (1000 GB) up to petabytes (1 million GB) in size. For example, Facebook, twitter, YouTube, etc. contains large quantities of data.
Velocity: It explains data that must be collected and analyzed rapidly to be useful, often at the same rate as they are collected in real time.
Variety: It refers to data consisting of many different forms, often brought together from varying sources. Now data comes in the form of emails, photos, videos, monitoring devices, PDFs, audio, etc.
Validity: Valid data is key to making the right decisions. The data must be correct and accurate for intended use.
