Hello all,
I am working on an assignment for a class over my winter break and need some help on the one requirement. I apoligze if its a dumb question but I'm not 100% sure what the professor wants and I'm hoping someone else may have an idea.

Essentially I have to build a VB App that tracks sales. That's the easy part, but he wants me to also "Show the ERD at Entity level at 3rd normal form."

I understand the 3NF part, but with respect to the ERD, I've seen several types and am a bit confused. (Mind you, I would ask him but he's not available over break). Do you think he wants the database diagram or something else?

Again, I'm sorry...I know this is a dumb question, but I'm having a brainfart.

Thanks in advance.
 
3NF simply means that you can't have any dependancies on any non key attributes so if you have your db setup already and it doesnt have any dependancies on non-key attributes, depending on the professor, you might be able to just print out the relationship diagram (assuming you're using Access).

How have you been submitting your ERDs in other exercises? Why not just follow the same format?
