we've told you before -- do not start new threads on the same homework problem in the hope of snaring some new unsuspecting passerby

by the way, your latest ER diagram attempt is way off the mark

no matter how much i tell you this is NOT home work,just practice questions because my exam is near you don't believe.i mean, do you think any teacher will let you more than 3 weeks(my last one is more than 3weeks older I guess) to do ANY type of a question? I do not know what is your issue

This is about converting to the 3rd normal form.I thought this is different from asking how to create an ER diagram
