Looking to understand the difference between instance tuning and database tuning.

What is the difference between these two tuning exercises?
I understand that an instance is memory based structures (logical) where as database consists of physical structures.
However, how does one tune a database the physical structure?
Does it have to do with file placements/block sizes etc...
Would you agree that a lot of that is taken care by ASM now in 11g?

What tools are required/available (third party as well as oracle supplied) for these types of tuning scenarios?

Appreciate any guidance on this.

YES as you said there are 2 parts
1/ Instance Tuning.
2/ Tune physical structure.( Query )

In My view

1/ Instance Tuning
1.1/ Allocation of memory for database processes released.
1.2/ take help of DBA.

2/ Tune physical structure.( Query )

2.1/ This consist of Query tuning
2.1/ Remove database design flows
2.3/ Developer Responsibility.( design team)
