For retrieving data from an Oracle database, how is .NET used to retrieve data using SQL statements? You can either use the OleDb data provider in the System.Data.OleDb namespace, or download an oracle-specific provider. AFAIK, there are a number of such providers, such as the one from MS (http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/001/940/msdncompositedoc.xml), from CoreLab (http://crlab.com/oranet/)...
and from Oracle itself (http://otn.oracle.com/tech/windows/odpnet/content.html).
From there on, you use the regular ADO.NET interfaces, which are homogeneous among all providers, such as IDbConnection, IDataReader, etc. A good overview of ADO.NET and its interfaces can be found in the .NET Show about it at http://msdn.microsoft.com/downloads/sample.asp?url=/MSDN-FILES/027/001/730/msdncompositedoc.xml .
