Lesson 5: Defining Relationships Between Dimensions and Measure Groups

In the previous lessons in this tutorial, you learned that database dimensions added to a cube can be used as the basis for one or more cube dimensions. In this lesson, you learn to define different types of relationships between cube dimensions and measure groups, and to specify the properties of these relationships.

For more information, see Dimension Relationships and Defining Dimension Usage Relationships.

This lesson contains the following tasks:

Defining a Referenced Relationship

In this task, you learn to link a dimension to a fact table indirectly through a dimension that is linked directly through a primary key–foreign key relationship.

Defining a Fact Relationship

In this task, you learn to define a dimension based on data in the fact table, and to define the dimension relationship as a fact relationship.

Defining a Many-to-Many Relationship

In this task, you learn to relate a fact to multiple dimension members through the definition of a many-to-many relationship between dimension tables and fact tables.

Defining Dimension Granularity within a Measure Group

In this task, you learn to modify the granularity of a dimension for a specific measure group.
