Overview of Oracle Data Provider for .NET (ODP.NET)

Oracle Data Provider for .NET (ODP.NET) is an implementation of a .NET data provider for Oracle Database, using and inheriting from classes and interfaces available in the Microsoft .NET Framework Class Library.

Following the .NET Framework, ODP.NET uses the ADO.NET model, which allows native providers to expose provider-specific features and data types. This is similar to Oracle Provider for OLE DB, where ADO (ActiveX Data Objects) provides an automation layer that exposes an easy programming model. ADO.NET provides a similar programming model, but without the automation layer, for better performance.

Oracle Data Provider for .NET uses Oracle native APIs to offer fast and reliable access to Oracle data and features from any .NET application.

The ODP.NET classes described in this guide are contained in the Oracle.DataAccess.dll assembly.
