What is big data analytics?

by Daniel J. Power
Editor, DSSResources.COM

Big data analytics combines buzz words and is a buzz phrase. The basic idea of this new business jargon is that the huge volume and variety of data being generated must be analyzed. Mashing together sources, big data analytics is defined as the analysis of very large, diverse, varied data sets known as "big data". "Big data" includes different types of data such as structured/unstructured and streaming/batch, and different sizes/volumes from terabytes to exabytes.

The goal of the "big data" analysis process is to use advanced analytic techniques to identify patterns, correlations, market trends, customer preferences and other useful information that can help organizations make more-informed business decisions. In general, the term analytics refers to quantitative and statistical analysis of data. Various sources identify three categories of analytics, including: 1) descriptive/reporting, 2) prescriptive, and 3) predictive. Sometimes diagnostic analytics is added as a fourth category. The goal of analytics is discovering useful information that supports decision making.

Common big data sources, include social media, mobile device files, and sensor analytics. Activity-generated data primarily comes from computer and mobile device log files (cf., Morris, 2012). Mobile devices, wearable technology, connected devices, sensors, social media, loyalty card programs and website browsing are generating large volumes of structured and unstructured data. This customer-generated data is creating new opportunities to analyze data and understand customers. If someone refers to social media analytics and mobile and sensor analytics, the reference is to the data source that is analyzed. For example, social analytics involves using sensor data, video data, social media data to gain actionable insights. Mobile data analytics comprises a set of tools that process, analyze, and visualize data originating from mobile devices.

There are four broad categories or types of big data analytics:

Descriptive/reporting – What is happening? What happened?

Diagnostic – What happened and why? Why did it happen?

Predictive – What will happen? What will happen next>

Prescriptive – What should happen next? What should I do?

These four categories or types of big data analytics are common to the more general terms business analytics or data analytics. Descriptive, diagnostic, predictive, and prescriptive analysis can be performed using many data sources as input, including "big data" sources like social media.

So if you are asked about the types of big data analytics, the question might refer to types of data used or the analytics used or both. If asked what type of big data analytics an organization is using, a specific reply might be "the company is using predictive analytics with social media data".

Business jargon can hinder understanding. Often all that is needed is a short and simple explanation of a "new" term. Big data analytics combines buzz words and is a buzz phrase. Analytics is important. The only change is the data used for description, diagnosis, prediction and prescription. Big data is different, but not inherently better than other data.
