Your task is to break this up into a list of "normalized" tables that you describe using the text-based "relational notation". You will need to break this example into as many separate tables as you feel is appropriate to remove all modification anomalies. Please submit your relational notations in an ordinary word document along with the sample data in a "grid". I'm expecting to see both PK and FK notations in your submission. Note: I'm not asking for a database... I'm asking for a list of tables in relational notation plus the sample data in rows/columns. Part One: Use text-based relational notation to describe each table/field Note: I am not yet requiring you to solve the "multi-column" problem Show PK and FK (use Microsoft Word's underline and italics tools) Part Two: Create a "grid" for each table with the all of the rows/columns of data for that table after normalization (to include PKs/FKs) Make sure you don't have any duplicate rows in your "grid" Note: You can just do…

So, it'd be a good idea to look at how the University Catalog and Semester Schedules uses data. You can't just look at the sample data... you'll also need to know things like "is a course always taught by the same professor, in the same room, at the same time?"
