You have been given a spreadsheet that contains details of invoices. The column headers for the spreadsheet are date, invoice number, invoice amount, invoice tax, invoice total, cust number, cust name, cust street, cust city, cust state, cust postal code, cust nation, product code, product price, product quantity, salesrep number, salesrep first name, salesrep last name, salesrep district, district name, and district size. Normalize this spreadsheet so it can be converted to a high fidelity relational database.

Ken is a tour guide for trips that can last several weeks. He has requested a database that will enable him to keep track of the people who have been on the various tours he has led. He wants to be able to record his comments about some of his clients to remind him of extra attention he might need to pay to them on a future trip  (e.g., Bill tends to get lost, Daisy has problems getting along with others). Some times people travel with a partner, and Ken wants to record this in his database.
