Presentation logic may consider converting or filtering certain data structures.
I.e. I have a menu structure pulled from a database, with multiple fields marked as "authorized only" or other indicative flags. I only need to display a few due to the current pass being done with "ANON_ACCESS" flag raised. Presentation logic would adhere to the flag and filter out any data that is not available to the anonimous visitor.
This way, I will not need to make multiple database queries for different flags, which means, the query results would be almost always in the DB server cache even if I'm not using page cache.
This will also reduce maintenance times. When menu structure or accessibility changes, I either don't need to change query, or need to only change it in one place.
