Summary
BI Semantic Models is a rich, scalable, and flexible model that can be deployed as part of a PowerPivot workbook or as Tabular Project using SQL Server 2012 Analysis Services in Tabular Mode. The BI Semantic Model can be viewed conceptually as a three-layer model consisting of the Data Model, the Business Logic, and Data Access.
BI Semantic Models are developed using the PowerPivot Excel Add-in or SQL Server Data Tools. The user interface of these two applications is very similar. Almost all features of a BI Semantic Model can be developed with the PowerPivot Excel Add-in, with the exception of roles and partitions available only through the SQL Server Data Tools development environment.
BI Semantic Models developed in PowerPivot workbooks can be deployed to SharePoint2010 PowerPivot Galleries to manage automatic data refresh.
In addition, BI Semantic Model Tabular Projects developed using SQL Server Data Tools, can be deployed to SQL Server 2012 Analysis Services running in Tabular Mode. The deployment options include:
- In-Memory
- In-Memory with DirectQuery
- DirectQuery
- DirectQuery with In-Memory
