Decision Support Objects (DSO)

Note

This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.

Important

Decision Support Objects is only included in Microsoft SQL Server Analysis Services to support existing unmanaged applications. For new managed or unmanaged applications, you should use Analysis Management Objects (AMO). For more information about AMO, see Analysis Management Objects (AMO).

The Decision Support Objects (DSO) library of Microsoft® SQL Server™ 2005 Analysis Services provides a robust set of Component Object Model (COM) objects and interfaces that you can use to create applications that can programmatically administer Analysis Services objects. With the DSO library, you can manage Analysis Services objects, such as servers, databases, data sources, dimensions, cubes, mining models, and roles. You can also administer security, process cubes and mining models, and so on.
