/**

 * Configuration DAO component <br>
 * <hr>
 *
 * This component is a fully functional configuration dao ready to use in order
 * to store in-application key-value-pairs. It is recommended to wrap
 * access to the key-value-pairs into a service bean which is used
 * to return type-safe variables (e.g. "myCount" in configuration is held as string "99")
 * but in your app your service should take care of the type and return myCount as an integer
 * value
 *
