2NF predicates that in a relation
Consider the following schema
Lot - (property_ID,
Here are the functional dependencies property_ID -> lot, lot_area, state lot, lot_area -> base_price state -> tax_rate
State, lot is a candidate key. But tax_rate is only dependent on a part of this candidate key, so we will move it to a new table.
Lot - (property_ID,
This schema in 2NF now.
