Explain how Excel can be used to design a database, including an example of a basic database layout that would be appropriate for, say, a gradebook for a graduating class’s overall GPA. Then, imagine that a business existed that used students’ information to propose specific colleges for them. What columns from the original spreadsheet would be kept? Propose at least four columns that would be added to a database for such a business, explaining how they would collectively help the business’s database function.
