Each of the following components is considered obsolete. While these components are still supported in this release of the Microsoft® Data Access Components (MDAC), they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
ODBC Provider (MSDASQL)
You are strongly encouraged to use one of the native OLE DB Providers instead of the Microsoft Open Database Connectivity (ODBC) Provider. Native OLE DB Providers provide better application stability and performance. Furthermore, native OLE DB Providers will be supported in the future, whereas MSDASQL will not have any new features added to it, will not be available on 64-bit, and will not be accessible from the OLE DB NET Data Provider.
Remote Data Services (RDS)
Remote Data Services (RDS) is a proprietary Microsoft mechanism for accessing remote data across the Internet or intranet. Microsoft is now shipping the Microsoft Simple Object Access Protocol (SOAP) Toolkit 2.0 that enables you to access remote data using an open, XML-based standard. Given the availability of the SOAP Toolkit 2.0, you should migrate from RDS to SOAP. The SOAP 2.0 Toolkit 2.0 also includes sample code for remotely accessing Microsoft ActiveX® Data Objects (ADO) Recordsets.
Jet and Replication Objects (JRO)
The Microsoft Jet OLE DB Provider and other related components were removed from MDAC 2.6. Microsoft has deprecated the Microsoft Jet Engine, and plans no new releases or service packs for this component. As a result, the Jet and Replication Objects (JRO) is being deprecated in this release and will not be available in any future MDAC releases.
AppleTalk and Banyan Vines SQL Network Libraries
If you are using the AppleTalk or Banyan Vines SQL network libraries, you should modify your applications to use one of the other SQL network libraries, such as TCP/IP. The AppleTalk and Banyan Vines SQL network libraries are being deprecated in this release and will not be available in any future MDAC releases.
16-bit ODBC Support
If you are still using 16-bit data sources, you need to migrate to a 32-bit data source. 16-bit functionality is being deprecated in this release and will not be available in any future MDAC releases.
