The Oracle.DataAccess.dll assembly provides two namespaces:
The Oracle.DataAccess.Client namespace contains ODP.NET classes and enumerations for the client-side provider.
The Oracle.DataAccess.Types namespace contains the Oracle Data Provider for .NET datatypes (ODP.NET Types).
The Oracle.DataAccess.Client namespace contains implementations of core ADO.NET classes and enumerations for ODP.NET, as well as ODP.NET specific classes.
The following tables list ODP.NET classes, enumerations, and types that are supported by the Oracle.DataAccess.Client namespace. The tables also indicated which classes are not supported in .NET stored procedures.
Table 1-1 lists the client classes.

Table 1-2 lists the client enumerations.
Table 1-2 Oracle.DataAccess.Client Enumerations
| Enumeration | Description |
|---|---|
| FailoverEvent Enumeration | FailoverEvent enumerated values are used to specify the state of the failover.
Not Supported in a .NET Stored Procedure |
| FailoverReturnCode Enumeration | FailoverReturnCode enumerated values are passed back by the application to the ODP.NET provider to request a retry in case of a failover error, or to continue in case of a successful failover.
Not Supported in a .NET Stored Procedure |
| FailoverType Enumeration | FailoverType enumerated values are used to indicate the type of failover event that was raised.
Not Supported in a .NET Stored Procedure |
| OracleCollectionType Enumeration | OracleCollectionType enumerated values specify whether or not the OracleParameter object represents a collection, and if so, specifies the collection type.
Not Supported in a .NET Stored Procedure |

| OracleXmlCommandType Enumeration | The OracleXmlCommandType enumeration specifies the values that are allowed for the OracleXmlCommandType property of the OracleCommand class. |
The Oracle.DataAccess.Types namespace provides classes, structures, and exceptions for Oracle native types that can be used with Oracle Data Provider for .NET.
Table 1-3 lists the type structures.
