The DataService<T> class does the basic integration of all components of the server system. A new data service that uses system defaults for authorization and caching is created by defining a class that derives from the DataService<T> class and by referencing a compatible data model.

The type of the DataService<T> must expose at least one property that returns an entity set that is an IQueryable<T> collection of entity types. This class must also implement the IUpdatable interface to enable updates to be made to entity resources.
