This is an E-R Diagram database question. I was asked by my professor to create an E-R diagram for my enterprise that involves an online coffee shop. After I created my E-R model, he told to adjust my original model, and the outcome has been this. However, I feel that the whole model is incorrect. Please help me get a better model. Without the model I can't create the relational, tuple, and domain calculus. Thank you.
