Hey, So how do you draw these things properly? I've looked in books and they don't explain it very well :/

I know all the relationships.

To my knowledge its not in the syllabus. It only refers to entities in a schema which is pretty straight forward.

If you have the excel study book its on pg 34

It's in the syllabus. I sort of understand it.

The HSC CSU site is quite useful.

Main things to identify are:

• Tables
• Relationships
• Primary key
• Foreign (Secondary) key
