VIEW Table

The VIEW entry stores a named view of the model or a paperspace layout. This stored views makes parts of the drawing or some view points of the model in a CAD applications more accessible. This views have no influence to the drawing content or to the generated output by exporting PDFs or plotting on paper sheets, they are just for the convenience of CAD application users.

Using ezdxf you have access to the views table by the attribute Drawing.views. The views table itself is not stored in the entity database, but the table entries are stored in entity database, and can be accessed by its handle.
