Explanation:
The above code was reached after the following considerations. Firstly, I reviewed the Sales Order Form
which was provided with this assignment. After reviewing the Order Form, I broke down the sections
into individual elements which I then converted into SQL table columns. This will allow orders to
populate as Rows into the Orders_1NF table. The primary key selected is derived from OrderID and
DonutID creating a composite key with the two data points which enforces complete uniqueness.
