• What are measures?− The value you are measuring, e.g. the
count of users with blue eyes, from WA state, etc.
− The question you are trying to ask
• What are measure groups? − Groupings of these measures within your
cube
− Typically define them by your business problem (e.g. Sales, HR, etc.)
• Cubes are a grouping of measure groups.
• What is a dimension?− It is what you want to categorize or pivot against
− E.g. How many users are from WA state?
− The dimension is geography, “WA” is the member
• What is a hierarchy?− How do you want to organize the members of
your dimension
− E.g. Geography has numerous levels such as country, state, and city
− Hierarchy is the organization of those levels such as City State Country

Pre-defined navigation paths through dimensional space defined by attributes
Attribute hierarchies enable ad hoc navigation
Why create user defined hierarchies then?› Guide end users to interesting navigation paths
› Existing client tools are not “attribute-aware”
› Performance
Optimize navigation path at processing time

Clustered decoding stores
Aggregation designer favors user defined hierarchies
Query language is MDX
