ACL and roles - Joomla! Forum - community, help and support

hi,

sorry if post not on right place, didn't know if "administration" forum or here, best place question.

my system have several types of users.

- supervisor:
this profile backups, manage other accounts , manage data (modify, update, delete, etc...)
e.g.: person having profile boss of company.
from point of view profile "admin" or "manager" role.

- application operators (they employees of supervisor). create, delete, modify , review data stored other profiles
from joomla point of view, can "manager"

- simple visitors of web portal (not registered).
from joomla point of view, "public" role.

for next 2, don't know kind of joomla profile have... editor, author, customer group, publisher ? both can store data database.

- customers of company/supervisor (registered account)
they typically write data through forms , result displayed on front end side "articles"

- students (registered account)
they write store data through forms, can print data using template , can view customers of company or operators wrote (like if blog of articles)

1. each of profiles should perform actions on front end side (i develop special component that, modules). know best/more suitable profiles in joomla ? or should create own profiles ? if yes, base relation (i mean parent-children relation) ?

thx.
