 # Spring Data DynamoDB ( Work in Progress ) #
 
 The primary goal of the [Spring Data](http://www.springsource.org/spring-data) project is to make it easier to build Spring-powered applications that use data access technologies. This module deals with enhanced support for Amazon DynamoDB based data access layers.
