Discussion 
A SHOW SCHEMA statement returns the description of every class defined in the federated database’s schema. (To return a description of a particular class, use the SHOW CLASS statement.)
The description of each class includes the namespace-qualified class name, its superclass (if any), and a list of attribute structures with the name and type information for each attribute in the class.
