Microsoft.AnalysisServices.Tabular Namespace

Provides an object API used to administer Analysis Services tabular server instances, databases, roles and assemblies. This namespace targets tabular databases at compatibility level 1200 or higher, where objects are described in tabular metadata as tables, columns, and relationships.

Script and managed code that calls into AMO should use the classes and members in this namespace to represent objects in a tabular model. When using this namespace, remember to also add a reference to Microsoft.AnalysisServices.Core.
