computed field:  A field in a database table with a value calculated from the values of other fields in the same or different tables of a single database.  You define the expression used to generate the values for a computed field using the same language and syntax employed for database queries.  The appropriate record values for use in a computed field are determined through primary and foreign key relationships or by element attachment.
