[FLOW3-general] Designing the system

[Dawid Pacholczyk]

Hello List,
  I have a small problem. I`m trying to design some small application 
and I need a controller that is handling couple of system behaviours 
like login the user or checking the priviliges.

This would be an object with out a Model...cause I won`t storage 
anything in DB. Now I know that this controller in some actions (like 
loging the user) need to make some checks in DB. How should I design this ?

For example I have

SystemController and should I create SystemRepository ? Is it proper for 
objects like this ?

Best regards,
Dawid Pacholczyk
