A set of columns in a table that match the primary key of another table.  
 They represent an explicit join of the two tables. Each foreign key 
 element points to it's table element (SQLI_TABLE_ELEMENT), a column in the local table (SQLI_COLUMN) and a primary key element of
a 
 foreign table (SQLI_PRIMARY_KEY). The primary key table element of the foreign table has the domain of that table, which makes the
connection.
