Overview

Kundera is a "Polyglot Object Mapper" with a JPA interface. The idea behind Kundera is to make working with NoSQL Databases drop-dead simple and fun. Kundera is being developed with following objectives:

  • To make working with NoSQL as simple as working with SQL
  • To serve as JPA Compliant mapping solution for NoSQL Datastores.
  • To help developers, forget the complexity of NoSQL stores and focus on Domain Model.
  • To make switching across data-stores as easy as changing a configuration.
