Power Pivot complements the SQL Server core BI components under the vision of one Business Intelligence Semantic Model ( BISM), which aims to integrate on-disk multidimensional analytics previously known as Unified Dimensional Model (UDM), with a more flexible, in-memory 'tabular' model.Īs a self-service BI product, Power Pivot is intended to allow users with no specialized BI or analytics training to develop data models and calculations, sharing them either directly or through SharePoint document libraries.Ī complementing feature to Power Pivot is Power Query (which for a short period was known as Get & Transform), which includes a new formula language called M. Prior to the release of Power Pivot, Microsoft relied heavily on SQL Server Analysis Services as the engine for its Business Intelligence suite. As a result, larger data models may not be compatible with the 32-bit version of Excel.

Practically, this means that Power Pivot is acting as an Analysis Services Server instance on the local workstation. Power Pivot uses the SSAS Vertipaq compression engine to hold the data model in memory on the client computer. DAX expressions resolve to T-SQL queries in the Formula and Storage Engines that drive the data model, abstracting the more verbose and tedious work of writing formal queries to excel-like formula expressions. DAX expressions allow a user to create measures based on the data model, which can summarize and aggregate millions of rows of table data in seconds. Power Pivot primarily uses DAX (Data Analysis Expressions) as its expression language, although the model can be queried via Multidimensional Expressions (MDX) in a row set expression.

This allows Excel to act as a Self-Service BI platform, implementing professional expression languages to query the model and calculate advanced measures. This allows a user to build a ROLAP model in Power Pivot, and use pivot tables to explore the model once it is built. Power Pivot extends a local instance of Microsoft Analysis Services Tabular that is embedded directly into an Excel Workbook. It is available as an add-in in Excel 2010, 2013 in separate downloads, and as an add-in included with the Excel 2016 program.
