Spring Data Introduction

What Is The Spring Data?

• Spring Data’s mission is to provide a familiar and consistent, Spring-based programming model for data access while still retaining the special traits of the underlying data store.
• It 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 subprojects 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.

Features

• Powerful repository and custom object-mapping abstractions.
• Dynamic query derivation from repository method names.
• Implementation domain base classes providing basic properties.
• Support for transparent auditing (created, last changed).
• Possibility to integrate custom repository code.
• Easy Spring integration via JavaConfig and custom XML namespaces.
• Advanced integration with Spring MVC controllers.
• Experimental support for cross-store persistence.
