How about using COM/ADO? This assumes ADO is installed on your clients - it's a lot
smaller than the BDE - but I think it uses ODBC??
If you are using Delphi 4 - Check the Delphi Direct - Tech Voyage - there is an entry
there for using Delphi and ADO.

I appreciate your idea, not because I am conservative, but I MUST make
the app very thin. BDE is absolutely unacceptable to install in
potential 15k clients. If anyone has the experience to program a driver
that links to Oracle, I am very glad to ask my boss to pay the above
average rate. I only need very simple functions like ExexSQL,
GetQueryRlt.
Also thank all who respond my silly question.
I am happy that I can learn in DUG.
Cheers
Yanbo

Call me a conservative....but why bother with all these
proprietary networking stuff? Bound data type controls are renowned for
making unscalable applications - the little bit of time saved in
throwing apps together is usually absorbed in the maintenance and slow
performance that these complicated technologies result in - especially
when they don't work.
DCOM and CORBA etc. don't achieve what they are supposed
to - which is transparent operation of applications over networks. I
haven't used MIDAS to be honest but I bet it's not the magic panacea
that the spec sheet describes.
The best approach is also the simplest. Implement your
own simple client-server library based on on straight TCP/IP or maybe
RPC, stream over some type of hash table object with a version numbering
scheme, and get your server to decipher the calls and talk to the
database.
The advantages are that it's transparent - you know
exactly when and what data
is being
sent across the network. It's easy to debug, you have
complete control so it's
easy to optimise
* you don't have to spend heaps of time evaluating crap third
party products which don't work.
And lastly no license fees or danger of your
client-server architecture becoming obsolete if the product you used
gets dumped or the company which makes it goes under.
