A table is a descendent of table T if it is a dependent of T or a dependent of a descendent of T.
Examples
TABLE1 has a foreign key that references the primary key in TABLE2, and TABLE2 has foreign keys that reference the primary keys in TABLE3 and TABLE4. TABLE2 is a dependent of TABLE3 and TABLE4. TABLE1 is a dependent of TABLE2. Therefore, TABLE1 is a descendent of TABLE3 and TABLE4.
