I know there are three users in APPS .
APPS , APPLSYS AND APPLSYSPUB.
what are they used for ? what is the difference between
APPLSYS AND APPLSYSPUB user ?
Does APPS own all the application objects ?
do all the users like from AP,GL,HR connect to oracle as APPS?
I know that all this is probably documented ,but i am really
tied up for time right now and would really appreciate it
if somebody here could give me some answers .

Thanks !
