Overview
You are a junior associate at Smarty’s School Supplies that offers bulk supplies ordering. Smarty’s has an audit scheduled next week and the auditor has asked that the databases be in tip top shape when he arrives! This means that all of the databases in Smarty’s system should be in third normal form. Your boss has tasked you with a portion of invoices from the month of September and has asked you find a way to convert the dataset into smaller tables that can easily reference each other. Good luck!

Instructions
First open the data file and determine what the “key” should be for each table; or in other words, what can uniquely identify each row of data. There should not be any repeat values as primary keys except for the master transaction file which should reference other tables. Make sure to split up the customer first and last name into two separate columns as well as the different parts of the address.
