Notice that the
Address
entity has a
customer
field. This field is of the type
Customer
, the entity we were just discussing.
Had we left the
Use Column Names in Relationships
checkbox
checked in the
Entity Classes from Database
wizard, the generated
customer
field would have been named
customerId
. In most
cases, unchecking this checkbox results in saner names for fields
used in entity relationships, as was the case here.
