Spring / Spring Data Access

What is 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.

Spring Data provides Abstractions (interfaces) that can be used irrespective of underlying data source.

interface EmployeeRepository extends CrudRepository<Employee, Long> {

Using the simple Employee repository, perform insert, update, delete and retrieval of EMPLOYEE entities from the database - without writing any database dependent code.
