This document provides an overview of big data concepts including what big data is, how it is used, and common tools involved. It defines big data as a cluster of technologies like Hadoop, HDFS, and HCatalog used for fetching, processing, and visualizing large datasets. MapReduce and Hadoop clusters are described as common processing techniques. Example use cases mentioned include business intelligence. Resources for getting started with tools like Hortonworks, CloudEra, and examples of MapReduce jobs are also provided.
