var sidebar_align = 'right';
var content_container_margin = parseInt('290px');
var sidebar_width = parseInt('270px');
Can anyone please explain to me the differences between weak and strong relationships and how they would appear differently in an ERD model? I tried to explain this to my students and they seem extremely confused.
