Big Data

Big Data refers to the massive amount of data collected over time that are difficult to analyze and handle using common database management tools. Big Data can be identified if they fulfill 3 V’s i.e. Velocity (large amount of data generated, which is taking more time in processing than its incoming rate), Volume (data collected over the time becomes huge) and Variety (unstructured, Semi-structured and Structured).

  • Unstructured Data- Emails, Blogs, Tweets, Social Networks, mobile data, Web pages and so on.
  • Semi-Structured Data- text files, system log files, XML files, etc.
  • Structured Data –Transaction data, RDBMS (Relational Database Management Systems), OLTP, etc.

Big Data deals with large scale data which cannot be effectively processed.
