A view that is defined is based on a set of one or more tables that may include relational tables or object tables. The view defines a presentation of data from the one or more tables as a set of objects that reside in the database. Data is read from the one or more rows of the tables based on the view, and is presented as a set of objects that reside in the database.

The view may specify which columns from the one or more tables contain values used to generate the object ids. A trigger may associated with the view.
