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.
