A rule defined on a column (or set of columns) in one table
that allows the insert or update of a row only if the value
for the column or set of columns (the dependent value)
matches a value in a column of a related table (the
referenced value). It also specifies the type of data
manipulation allowed on referenced data and the action to
be performed on dependent data as a result of any action on
referenced data.
