Identify measures

Fact tables are modeled around a specific business process. The measures in a fact table, or facts, are the numeric representations of the events that occur in the business process.

Examples of measures in the Sales business process include the Quantity of Items Sold and the Sales Amount.

Measures can be identified by analyzing what a business wants to track about a specific business process.

For example, a business might be interested in how many units of a specific product are sold and how much revenue it represents.

In addition, measures can be identified from strategic organizational goals and indicators known as key business metrics and key performance indicators (KPIs). Some of the metrics or KPIs related to the Sales business process include Sales Growth, Profit Margin, and Sales Actual vs Target.

A rule of thumb to identify a value as a measure is to test if the value can be summed up by one or more dimensions or aggregated over time.
