Abstract

Earlier, the transactional and operational data were maintained in tables and stored in relational databases. They have formal structures and schemas. However, the recent production and flow of multi-structured data has inspired many to ponder about the new ways and means of capturing, collecting, and stocking. E-mails, PDF files, social blogs, musings, tweets, still photographs, videos, office documents, phone call records, sensor readings, medical electronics, smart grids, avionics data, real-time chats, and other varieties of data play a greater role in presenting highly accurate and actionable, timely insights for executives and decision-makers. The chapter provides an insight into the big data phenomenon, its usability and utility for businesses, the latest developments in this impactful concept, and the reference architecture.

Big Data Analytics

What is Big Data Analytics?

Big Data Analytics is the process of examining large amounts of data of a variety of types (Big data) to uncover hidden patterns, unknown correlations and other useful information. In other words, Big data Analytics is the use of advanced analytical techniques against very large diverse data sets that includes different types such as Structured/Unstructured and Streaming/Batch and different sizes from terabytes to zettabytes.

Figure 1 shows how a Big data processing is done. By facilitating data scientists and other users to analyze huge volumes of transactional data as well as data from other sources which are left untapped by conventional Business Intelligence(BI) Programs, Big data analytics help the organizations to make better business decisions.

These other data sources may include Web server logs and Internet click stream data, Social media activity reports, Mobile-phone call detail records and information captured by the sensors.

Some people exclusively associate Big Data and Big data Analytics with unstructured data. Consulting firms like Gartner Inc. and Forrester Research Inc., consider transactions and structured data to be valid forms of Big data.

Big Data Analytics can be done with the software tools commonly used as part of advanced analytics discipline such as Predictive Analytics and Data Mining.
