NoSQL

NoSQL is a classification of database systems that do not conform to the relational database or SQL standard. They have various roots, from clustered internet databases, to object databases, XML databases and legacy databases. They have become recently popular because of their use in large scale disturbed databases in Google and Amazon.

There are various NoSQL databases including:

  • Mongo DB
  • Oracle NoSQL
  • Casandra
  • Google BigTable
  • Cache DB

As of EclipseLink 2.4, EclipseLink has added JPA support for NoSQL databases, initially with support for MongoDB and Oracle NoSQL.
