Model star schemas using a sequence of join nodes.

Aggregate at the lowest possible node.

Include all data flow logic within one calculation view.

Avoid defining joins on calculated columns.

Create a level hierarchy and assign it to the variable. Ensure the variable's reference column is the top level of the hierarchy.

Create a parent-child hierarchy and assign it to the variable.

Ensure the variable's reference column is the parent attribute of the hierarchy.

Create a parent-child hierarchy and assign it to the variable.

Ensure the variable's reference column is the child attribute of the hierarchy.

Create a level hierarchy and assign it to the variable.

Ensure the variable's reference column is the leaf level of the hierarchy.
