See the attached file.


Let us start with a single table with all columns in it. Let's remember that, in all tables candidate keys (also known as Primary Keys) are in BOLD

Let's call the below table OrderInfo table:

Table OrderInfo:



The following FDs (functional dependencies) hold on the above table:

Order_Id -> Customer_id, Order_date, Order_number
Item_Id, Order_Id -> Item_Name, Item_Qty, Item_Unit, Item_out, Item_received
Customer_id -> Customer_Name, Customer_Address, Customer_City, Customer_State, Customer_zip
Item_Id -> Item_name, Item_qty, Item_unit..,

Primary key of the above table is a composite candidate key Order_id and Item_id

Clearly, this table is in 1 NF, but it is not in 2NF, so obviously not in 3 NF.

The table is not in 2 NF because we have FDs with part of candidate key Order_id and Item_id and also Customer_id

So, we have to separate the fields according to the FDs and create more tables.

Hence, at first we take the FD

Customer_id -> Customer_Name, Customer_Address, Customer_City, Customer_State, ...

Then, we need to put the below fields in Customer table

Customer_id ...
