With the emergence of the World Wide Web and Internet-based technologies as the basis for the new “social media”
generation, great amounts of data are being stored and analyzed. Social media refers to Web and mobile technologies
that enable “anywhere, anytime, always on” human interactions. Websites such as Google, Facebook, MySpace,
Twitter, and LinkedIn capture vast amounts of data about end users and consumers. These data grow exponentially and
require the use of specialized database systems. Over the past few years, this new breed of specialized database has
grown in sophistication and widespread usage. Currently, this new type of database is known as a NoSQL database.
The term NoSQL (Not only SQL) is generally used to describe a new generation of database management systems that
is not based on the traditional relational database model. You will learn more about this type of system in Chapter 2,
Data Models.
