Oracle Provider for OLE DB
OLE DB is a Microsoft data access standard accessed through ActiveX Data Objects (ADO), Visual C++, and any client that can use OLE DB. The goal of the Oracle Provider for OLE DB is to have a high performance and rich feature mechanism for data access to Oracle databases.

The Oracle Provider for OLE DB allows high performance and reliable access to Oracle databases for ADO- or OLE DB-enabled applications. Current ADO and OLE DB programmers can easily migrate to the Oracle provider because it complies with the OLE DB specification. Additionally, the provider allows access to Oracle-specific features, including PL/SQL stored procedures, LOBs, and RAC. The Oracle OLE DB Provider supports transaction enlistment through the Oracle Services for MTS. The Oracle Provider for OLE DB also offers full support for .NET via the Microsoft OLE DB .NET data provider. With OLE DB .NET, applications can access the Oracle database from any .NET programming language.

The provider now supports 64-bit Windows natively, including Windows x64 and Windows Itanium. Download the 64-bit Oracle Provider for OLE DB from OTN.
