As Goat CO suggested, you could create two reference tables on this one, namely, Landlord
and LandLord Group
. And then of course relate it to your main Table.
So, in that case you could have three tables, namely, LandLord, LandLordGroup and probably LandRental tables.
You could probably have these Tables
and Fields
then:
Table : LandLord
Fields : LandLordID, LandLordName
Table : LandLordGroup
Fields : LandLordGroupID, LandLordGroupName
Table : LandRental
Fields : LandRentalID, LandLordID, LandLordGroupID, Quarter, Year, Estimate
Do not take literally the no repeating groups
in 1NF
(1st Normal Form) rule here because the repeating groups here are now all foreign keys
from reference tables (i.e. LandLord, LandLordGroup). Additionally notice that I added a Primary Key
(LandRentalID) now in your main table (i.e. LandRental).
