In simple terms, data is defined as unprocessed data capable of being stored and transmitted in the form of electronic signals. Unfortunately, today, we have to look at alternatives other than data due to the increased necessity to store and process more than terabytes of data daily. To address this problem, big data is adopted nowadays in Amazon, Facebook, Spotify, and many more. Let us dive deep into big data to get a better image.
Data that is impossible to process, store, or analyse using traditional methodologies is generally referred to as Big Data. The National Institute of Standards and technology report defines Big Data as follows,
“Extensive datasets primarily in the characteristics of volume, velocity, and variability that require a scalable architecture for efficient storage, manipulation, and analysis.”
Moreover, Volume, Velocity, and Variety, or in other words, 3V, forms the foundation of Big Data which gained momentum in the early 20s. With the rapid industrial evolution, Big data comes in handy as it combines all 3 data types:
structured, unstructured, and semi-structured. In addition to the 3Vs defined, we can further categorize big data as 5Vs to include Value and Veracity.
Suppose we put the term big data analytics into a simple and understandable form that conveys the idea. In that case, Big data analytics uses advanced analytic techniques against large, diverse big data sets. Data for analysis include structured, semi-structured, and unstructured data, from different sources and of various sizes, from terabytes to zettabytes, to extract meaningful insights, such as hidden patterns, unknown correlations, market trends, and customer preferences, and arrive at meaningful conclusions.
