WORKSPACE
Use Developer Tier pricing
Remember to pause your machines

Dimensions
Wide and shallow
Describe facts
Can contain hierarchies
Can contain calculated columns
2017-04-08
| Phillip Labry | Azure Analysis Services
Hierarchies
Predefine common hierarchies for the users
Hierarchies are defined from largest group to smallest
Year
Quarter
Month
Hide columns used for hierarchies where appropriate
2017-04-08

Fact Tables
Deep and narrow
Mostly measures(Numbers)
Keys to dimensions(Ints)
Natural repository for calculated measures

Calculated columns and Measures
• Created in the model only
• Calculated measures execute when called based on filter
context
• Calculated columns are created on data load and persist in
memory

Tips for development
Clean table names on first import
Settle on column names before creating any calculated
columns or measures
Flatten out snowflakes where possible
Avoid creating calculated columns for intermediate
measures
Use views for source data
Use meaningful and verbose names
Use attribute properties and formatting
