12.3. View

A view is a virtual table. A view contains rows and columns,like a real table. The fields in a view are fields from one or more real tables from the source or other view models. They can also be expressions made up multiple columns, or aggregated columns. When column definitions are not defined on the view table, they will be derived from the projected columns of the view's select transformation that is defined after the AS keyword.

You can add functions, JOIN statements and WHERE clauses to a view data as if the data were coming from one single table.
