Produce a set of relations (equivalent to the Finkelstein entity list) in third normal form (3NF) from the following un-normalised relation. Show your working and entitles for 1NF, 2NF and 3NF. You must use the Finkelstein methodology as used in the study book and tutorials. Freight Office (Branch name, address, opening hours, office contact, ((Freight id, item, category, package, weight, dimensions, ship-by date, receive-by date, ((Item description, sender id, sender name, sender contact, contact address)) )), total cargo, ((receiver id, receiver name, receiver contact, receiver address)), destination id, destination country code, destination state, destination city, distribution centre, distribution contact)

Notes:

1. Freight Office uniquely identifies a freight office branch.

2. A freight office has several freight items, and the total cargo outbound from the freight office can be calculated by this relationship.

3. ship-by date is the dispatch date when the item batch cargo has been shipped from the office.

4. receive-by date is the expected date when the item batch cargo has been received by the destination port.

5. Each item may have one or multiple senders, however individually, they should only be shipped to one receiver.

6. There are also many receivers of the cargo and only one distribution centre at the shipping destination.
