Yes, Sling accesses the repository directly and maps it into its own 
abstraction called the Resource tree. Each Resource retrieved from the 
Resource tree by means of the so-called ResourceResolver can be adapted 
to other objects.

For example if a Resource is backed by a JCR node, you can adapt it to 
the Node interface and get the backing node. If you employ Jackrabbit 
Object Content Mapping (OCM) you may also adapt to the object classes 
mapped by the content. This gives you seemless access to the repository 
data as raw JCR items or as mapped business objects.

Hope this helps.

Felix
