Am a little rusty on all of this...

So I have decided to use MySQL Workbench to create ERD's for our project for now.

When I go into Workbench and choose "New", it seems to create a new "Model" and a file ending in ".mwb"

But I also see that a section called "Physical Schemata".

Workbench seems to let me create tables with or without creating a "Physical Schema"?!

So my questions are...

1.) What is a "Model"?

2.) What is a "Physical Schema"?

3.) What happens if I create Tables outside of a "Schema"?

If someone can help me get my grounding that would be great!
