You could try looking at MSDN: There is an article there on Using .NET Framework Data Provider for Oracle to Improve .NET Application Performance[^] which also gives links to download the data provider which will link to the oracle database. --Colin Mackay-- "In the confrontation between the stream and the rock, the stream always wins - not through strength but perseverance." (H. Jackson Brown)

If you are going to have to *learn* either C++ or C#, i'd suggest C#. However C# can very easily handle this with the .NET data provider classes. The link below is to an article on using the Oracle Data Provider for .NET. Should give enough examples to help your decision out. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/manprooracperf.asp

If you are creating a COM object, go with C++ and use ADO to talk to Oracle.
