Sales Invoice
Consider a typical sales invoice that would include the following information. Design a single table to hold all of the information required to store an invoice including this information. Next, apply normalization to reduce this table to third normal form. Prepare a Word document showing the original and final tables. Include a short summary (2–3 paragraphs) of the problems with the original single table design and how normalization improved the design.
