Re: ER diagram design

I know in this age of video fetishism, this will sound like heresy, but the ER diagram is not the starting point of database design.

Such diagrams are lossy representations of complete db designs.

First, work out the required tables and columns &c on paper or in a text editor, following a systematic method like that described at https://www.artfulsoftware.com/dbdesignbasics.html.

When you're as far as step 4 in that sequence, you might start on the ER diagram. Or, you can wait till you get to the end, your choice.
