The hardest part of creating a database is deciding how it should be structured. What tables do you need to hold information? How can or will the tables be related?
Of course, I am discovering that I am my greatest distraction in getting this assignment done. It was challenging to come up with a third table for the assignment, and now that I have, I'm making queries, and attempting calculations.
I am quickly realizing that a database is a work in progress and constantly evolving.
