Big data refers to large and complex datasets that exceed the processing capabilities of traditional data management and analysis tools. These datasets are characterised by three main attributes often referred to as the "3Vs":
Volume: Big data involves vast amounts of data generated from various sources, including business transactions, social media interactions, sensor data, and more. The volume of data can range from terabytes to petabytes and beyond.
Velocity: Big data is generated at high speed and requires real-time or near-real-time processing and analysis. Data streams continuously from sources such as social media feeds, IoT devices, and online transactions, necessitating rapid processing to derive insights and make timely decisions.
Variety: Big data encompasses diverse data types, formats, and structures, including structured, semi-structured, and unstructured data. This includes text, images, videos, sensor data, geospatial data, and more. Managing and analyzing such heterogeneous data sources pose significant challenges.
In addition to the "3Vs," big data is often associated with a fourth "V" - Variability, which refers to the inconsistency or unpredictability in the data's arrival rates and formats.
Big data analytics involves the use of advanced analytics techniques, such as machine learning, data mining, and predictive modelling, to extract insights, identify patterns, and make data-driven decisions from large and complex datasets. Organisations across various industries leverage big data analytics to gain a competitive edge, optimise operations, enhance customer experiences, and drive innovation.
