a process that occurs on EVERY page

[eluser]deco10[/eluser]
I need to do some processing for my menu on every page of my site.
It seems silly to call a function in every function in the controller. The process will likely involve a data base call.

How should I approach this?

read up on creating core classes in the user guide, that's probably the easiest method though not the only one.

Autoloaded model or library that calls the necessary function for retrieval in its constructor and saves its output as a property?
