My third question of the day:

DataSets are virtual databases in the memory. I get that part.
But I want to know if this is the servers memory or the users memory.

datareader is forward only and read only, so it's faster and more efficent
if it satisfies your needs.
Otherwise, you have to use dataset.

All those code is run on server side, so of course it is server's memory.
What client sees is only html.
