Delphi connection ?

I have to develop a client/server application, heavily transaction oriented, that will serve around 100 users and database traffic will be intense (lot's of reads, updates, inserts....).

Development environment is Delphi 2007.  I know there are a few commercial components available, but I was wondering if ODBC could do the job ? 

So, my question is, if ODBC is intended to be used for that ?  Many simultanous connections, lots of inserts, updates ?

The thing you always hear about ODBC is, that it is very slow ?

 

Many thanks in advance,

Best regards,
