Detailed Description

Class used to represent the system views.

This class is a singleton used to represent meta data of the system views, i.e., the views that are available through the information schema.

Note

The registry currently only stores the view names and their (dummy) classification.

The singleton contains an instance of the Entity_registry class, and has methods that mostly delegate to this instance.
