Download Oracle Data Provider for .Net

Object Relational Mapping (ORM) technologies enable developers to write object oriented code to a conceptual model of their data rather than accessing the database directly. Two popular ORMs for .NET are NHibernate and Microsoft's Entity Framework. Both solutions integrate with Microsoft Visual Studio, leverage designers, wizards and code templates and require a layer of code to handle the mapping to an Oracle database.

Oracle Data Provider for .NET (ODP.NET) and Oracle Developer Tools for Visual Studio provide that mapping layer as well as Visual Studio enhancements to enable .NET developers to target Oracle Database with their Entity Framework applications.

ODP.NET features optimized ADO.NET data access to the Oracle Database. ODP.NET allows developers to take advantage of advanced Oracle Database functionality, including Real Application Clusters, XML DB and self-updating client caches.

ODP.NET makes using Oracle from .NET more flexible, more stable and much faster. ODP.NET includes many features not found in other .NET drivers, including flexible LOB data types, self-tuning, run -time connection load balancing, fast connection failover and Advanced Queuing.

You can download the latest ODP.NET production release in ODAC Release 2, from: . This release includes fully managed ODP.NET, multitenant database support, Identity column support, native PL/SQL Boolean data type and Transaction Guard.

ODAC includes Oracle Data Provider for .NET, Oracle Developer Tools for Visual Studio (ODT), Oracle Provider for ASP.NET, .NET stored procedure support, as well as Oracle data access software for windows.
