Fields are usually presented to users in main listing tables and on add/edit forms, or used for various control structures in each controller. The pseudo_value statement provides a way to use 'pseudo' columns for these various purposes. The definition of a pseudo column is a complex query/field that is not actually part of the table itself, but has been given an alias so that it can be treated as if it were.
