Big Data is a term used to describe a collection of data that is huge in volume and yet growing exponentially with time and also beyond the ability of traditional data management tools to capture, manage and process the data with low latency.

What is Big Data Analytics?

Big Data Analytics is the process of using efficient and advanced analytics techniques to collect, organize and arrange a huge amount of data sets (big data) which include structured, semi-structured and unstructured data from various sources, and in varied sizes from terabytes to zettabytes to underline information that would have been otherwise hidden. Information’s such as hidden patterns, correlations, market trends, customer preferences and other insights, that can help organizations make informed and better business decisions.

Big Data Analysis allows researchers, business users and analysts to make better, faster and informed decisions through the use of data that was initially not accessible and couldn’t be used.

These days, most business users now use advanced analytics techniques such as text analytics, machine learning, predictive analytics, data mining, statistics and natural language processing in order to gain new insights from previously untapped data sources independently or together with existing enterprise data.

Big data analytics also helps organizations harness their data and use it to identify new market opportunities which in the long run leads to more efficient operations, smarter business moves, higher profits and satisfied customers.

Brief History

The term big data was first used to refer to increasing data volumes in the mid-1990s. Big data analytics which started in the 90s came into existence as a result of the need to respond to the increase in big data.

The concept of “big data” has been around for a very long time, even long before the term “big data”, was coined in the 1950s. Businesses were using basic analytics (i.e. examining major numbers in a spreadsheet manually).

Today, most companies now understand that if they capture all the data that streams into their businesses, they can apply analytics and get important value from it, hence, the need for big data analytics.

Early Use

At first, as the Hadoop ecosystem took shape and started to mature, big data applications were majorly the house of large internet and e-commerce companies like Google and Facebook which took advantage of big data analysis. But between 2009 and 2010, healthcare companies, retailers, manufacturers and banks began to see the value of also being big data analytics companies.

In our world today

Today’s advances in analyzing big data allow researchers to decode human DNA in minutes, predict where terrorists plan to attack, determine which gene is mostly likely to be responsible for certain diseases and, of course, which ads you are most likely to respond to on Facebook.

Difference between data analysis and big data analytics

The main difference between regular data analysis and big data analytics is the speed and efficiency that big data analytics offers to most organizations and businesses which is essential for today’s companies to find success as compared to few years ago, where a business would have gathered information, run analytics and unearthed information that could be used for future decisions.

The ability to work faster, stay agile, and discover insights faster and efficiently gives organizations today a competitive edge they didn’t have before and also translates into immediate business decisions that can determine a win.
