We use them for being sure that a field in a table always references a
valid entry in another table. For example, you've got your sales table,
which contains a customer_id field which, of course, must reference a
valid customer in the customers table. So, you use a foreign key for
this field. In oracle, you can't insert a value in this field which is
not in the customers table, and, most importantly, you can't delete a
customer which has rows referencing it in the sales table. This is quite
safe for 

I don't know where to find generic docs, but if you look at some oracle
docs, you'll see what it is.

You mean the properties are working?
