Spring Data provides a familiar and consistent, Spring-based programming model for data access

Spring Data makes it easy to use data access technologies, relational and non-relational databases, map-reduce frameworks, and cloud-based data services. This is an umbrella project which contains many sub projects that are specific to a given database. The projects are developed by working together with many of the companies and developers that are behind these exciting technologies.
