working with direct Oracle access components in delphi

I am creating one delphi application w开发者_Python百科hich is fetches data from database. For accessing the database through delphi i am using DOA components. Is it possible to run the built exe on any machine? If not then what are the option available? thanks for the help.

Yes, it is possible to run your exe on any machine. You only need Oracle client to be installed.

The DOA components are not free as you can tell by reading their website. So you'll have to purchase these components, and you'll have to install and configure the Oracle client on each machine.

But they may still be your best option. Alternatively, you can use ADO, but the ADO Oracle driver from Oracle apparently is instable, while the ADO Oracle driver from Microsoft is much stabler, but doesn't support blobs. These problems are solved in ADO.NET, but that won't do you any good using Delphi 5.
