Table reference

Overview

The Reference page defines a relationship between two warehouse tables. It stores the cardinality, join type, table pair, inheritance options, aliases, reference statement, column mapping, and transformation usage for the selected table reference.

Function

Use Cardinality, Join, Table 1, and Table 2 to define the basic relationship between the two tables.

Use Description, ParentDescription, and Reference Statement to document or define the reference statement shown in the editor.

Use the inheritance options to control how metadata inheritance is applied to the reference. Auto created indicates that the reference was created automatically, and Inactive disables the reference without removing it.

Use the Columns grid to map both sides of the reference. The Used in transformations grid shows where the reference is used by transformations.

Access

Open the References list from the DWH toolbar, then open an existing reference record from the list.
