The table provides a spreadsheet with sample data for the Invoice table. Is there any redundant data in that table? Figure out a way to eliminate the redundant data by changing the design of the database. (Hint: Add another entity that would contain the redundant data and link that entity to the Invoice entity through a relationship). Make that change on the ER diagram.
