I wonder what is the difference between Class diagram and ERD (Entity relationship diagram).
According to me, the difference is, the purpose of each diagram.
Class diagram : to show relations between objects in OOSE
ERD : to show relations between table
and i made a speculation (my version), if i've made a class diagram so i don't need to make ERD, because i can build my tables using object in class diagram.
is that right? Or is there anybody can give better explanation for these two?
thx for your opinions
