It uses your existing relational model, so there is usually no need to create a star schema (which usually means using ETL to create new dimension and fact tables in a Data Mart or Data Warehouse). I would recommend going with Tabular if possible, as it is better to use for these reasons: If you need any of the following features, you must use Multidimensional: Actions, Custom Assemblies, Custom Rollups, Custom Drillthrough Actions (but BIDS Helper adds support for actions in a PivotTable in Excel but not in PerformancePoint), Linked objects, or Translations.If your solution requires complex modeling, choose Multidimensional.If you need Many-to-Many relationships, choose Multidimensional (can be done in Tabular but difficult).
If you need extreme speed and consistently fast query time, choose Tabular.If you need complex calculations, scoping, and named sets, choose Multidimensional.If you need access to many different external data sources, choose Tabular.If you need writeback support, you have to use Multidimensional.If your dataset is extremely large, go with Multidimensional.If you want to use Power View, you have to use Tabular.If you want to use DAX, you have to use Tabular.Well, there is no clear-cut answer, but there are some factors that can make you choose one over the other:

To access the release candidate of the extensions in Visual Studio, you may do so by creating a “private gallery” and entering the following settings. If you'd like to have early access to release candidate builds before they are published to the VS Gallery, we’re making available to give customers an opportunity to provide feedback prior to finalizing releases. Visit for the latest information, tips, news, and announcements about Analysis Services directly from the product team. If you have configured Visual Studio to use source control, you can use check in/check out from Solution Explorer. Among other things, you can import existing models from a server or start a new, blank model project.Īnalysis Services modeling projects integrate with source control, such as Team Foundation Server and many third-party source control plug-ins. After creating a new model project by using one of the templates, you can begin model authoring by using the designer tools and wizards included in the chosen project type. Package includes support for Tabular and Multidimensional projects.
