Fact table

Overview

Fact table identifies a data mart fact output in AnalyticsCreator. Use this table type for quantitative business events, transactions, and measurements that connect to dimensions in analytical models.

Function

A Fact table represents a data mart fact view. The fact can be maintained as a non-historized output or as a historized output when the model needs to preserve changes over time.

In the table editor, Fact table is handled as a view-based data mart object. The table name and generated structure are protected from direct table-definition editing, while business metadata, analytical settings, and measure-related information remain available for review and maintenance.

Because Fact table is a data mart type, the editor shows analytical controls such as OLAP perspective, Export to OLAP, Hidden in OLAP, OLAP Category, OLAP column settings, DAX columns, and measures. The Table Definition tab is not editable because the fact output is generated as a view.

Access

Open an existing Fact table from the Tables list or from the navigation tree. Fact definitions can also be maintained from the model area, where a fact can be created with measures and related dimensions before it is generated as a data mart transformation.
