Here is a link to a Entity-Relationship table made for my Information Science Course...
The example has a fictional list of customers and their shopping orders in a fictional "Ma and Pop Store."
The small village of Mexico is a real town in upstate New York, but the streets provided are not real streets in the town (a few names are a bit of a spoof).
I created these tables with the help of a Windows Program called "ACCESS" (the program will be needed to open the file).
