DATA MODELING FOR ANALYSIS
![Page 12: Realizing Business Insights with PowerPivot](https://reader036.vdocument.in/reader036/viewer/2022062315/56816211550346895dd23d62/html5/thumbnails/12.jpg)
OLAP Data Modeling• OLAP Data Models
generally take the form of a “Star” Schema
• Two kinds of tables• Dimension• Fact
• Fact tables have a 1:M relationship to all Dimension tables.
![Page 13: Realizing Business Insights with PowerPivot](https://reader036.vdocument.in/reader036/viewer/2022062315/56816211550346895dd23d62/html5/thumbnails/13.jpg)
Data Modeling for Analysis• PowerPivot blurs the
line between dimensions and facts.
• Only requires that a user understand where the numbers are and how they want to slice them.
• Can join together many disparate data sources.
• DAX allows you to manipulate the data and build custom calculations.
