Chapter Preview


Big data is a buzzword used to describe and transfer a massive volume of structured and/or unstructured data into knowledge. It is so huge that it is very difficult to process it using traditional database and software techniques. Big data helps companies to improve the performances of their applications and make faster intelligent decisions. Big data refers to Petabytes or Exabytes of data consisting of more than Gigabytes to Terabytes of records of more than lac users, all from different sources. These sources may include: web, sales, customer contact center, social media, mobile data etc. One must be familiar with the other terms of data as shown in Table 1. Big data is always not referring to big volume of data but also refers to the technology that deals with the large amount of data and the infrastructure needed to store that data. When dealing with larger data sets organizations face difficulties in being able to capture, organize, manage and integrate big data as standard tools and procedures are not designed to search and analyze massive data sets. It may take so many minutes/days/years to transfer the data from one location to other. Businesses or enterprises expects more fast processing and transfer of data to perform different operations on it. Ninety percent of data currently available in the world is generated in last few years.
