DATA MODELING FOR ANALYSIS
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.
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.
