I have a simple question about the client program design.
If I have an login authetication database for some topic, and
some relative C programs included.
My problem is, should I connect-query-free-disconnect for each
authetication process, or just to check the connection first, and
re-connect only if the connection is lost?
I don't understand the inside story, but I do know that there is
something called 'presistent connection' for frequent database
If the latter method is used, then where is the 'connection' when
one process exit? and how the new process use/know the 'presistent'
Thanks for your help, if I made something wrong, please tell me.
