What is big data?

Big data refers to massive, difficult-to-manage data quantities – both organized and unstructured – that inundate enterprises on a daily basis. It is a collection of structured, semistructured, and unstructured data that may be mined for information and utilized in machine learning, predictive modeling, and other advanced analytics applications. But it's not just about the type or quantity of data; it's also about what companies do with it. Big data may be evaluated for insights that help people make better judgments and feel more confident about making key business decisions.

Big data processing and storage systems, as well as technologies that facilitate big data analytics, have become a standard component of data management infrastructures in enterprises. Big data is typically described using the three Vs:


Big data is massive. Big data is measured in petabytes and zettabytes, whereas regular data is measured in megabytes, gigabytes, and terabytes.

According to EMC research, the digital world doubles in size every two years, which was at 44 trillion zettabytes by 2020.

The architecture for processing this type of data is provided by big data. Without the correct storage and processing choices, mining for insights would be difficult.


Everything about big data is quick, from the time it takes to produce it to the time it takes to evaluate it.

Companies and organizations must be able to harness this data and develop real-time insights from it; otherwise, it would be useless. Real-time processing enables decision-makers to move fast, providing them a competitive advantage.

While certain types of data may be batch processed and kept relevant over time, most of the big data comes in at a rapid pace and needs- immediate intervention in order to get the best results.


Approximately 95% of all large data is unstructured, which means it does not fit neatly into a typical model. A huge data stream might include everything from emails and movies to scientific and meteorological data, each with its own set of characteristics.

Importance of big data

Companies utilize big data in their systems to enhance operations, provide better customer service, generate targeted marketing campaigns, and take other activities that can raise revenue and profitability in the long run. Businesses who use it correctly can get a competitive advantage over those that don't because they can make better-informed and faster business decisions.

Big data, for example, offers firms with important consumer insights that they can utilize to improve their marketing, advertising, and promotions in order to boost customer engagement and conversion rates. Consumer and corporate purchasers' developing preferences may be assessed using both historical and real-time data, allowing organizations to become more responsive to their desires and requirements.

Medical researchers and clinicians utilize big data to uncover disease indicators and risk factors, as well as to diagnose diseases and medical problems in patients. Furthermore, data from electronic health records, social media sites, the internet, and other sources are combined to provide healthcare organizations and government agencies with up-to-date information on infectious disease threats and outbreaks.
