Yes, all other applications which supports EXIF, IPCT ...

Yes, for performance and for people who do not want to write the 
metadata in the pictures and for picture format which can not contain 
metadata.

Yes, it is an option, look in the preferences. It is also a question of 
the first time wizard when you lunch digikam for the first time.

Hope this helps.
