 This application has been built to store the same domain objects in one of a variety of different persistence technologies - relational, document, and key-value stores. This is not meant to represent a realistic use case for these technologies, since you would typically choose the one most applicable to the type of data you need to store, but it is useful for testing and experimenting with different types of services on Cloud Foundry.
 
-The application use Spring Java configuration and [bean profiles](http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html) to configure the application and the connection objects needed to use the persistence stores. It also uses the [Spring Cloud Connectors](http://cloud.spring.io/spring-cloud-connectors/) library to inspect the environment when running on Cloud Foundry. See the [Cloud Foundry documentation](http://docs.cloudfoundry.org/buildpacks/java/spring-service-bindings.html) for details on configuring a Spring application for Cloud Foundry.
