...The purpose of these /keys/ is so that data can be related across 
tables, without having to repeat data in every table--this is the power 
of relational databases. For example, you can find the names of those 
who bought a chair without having to list the full name of the buyer in 
the Antiques table...you can get the name by relating those who bought a 
chair with the names in the AntiqueOwners table through the use of the 
OwnerID, which / relates/ the data in the two tables....
