Creating and Editing Data Lineage Data Flows
The Data Lineage Data Flow organizes and encapsulates data transformations and the source tables and columns
used in the transformations to produce the target data. Multi-tiered mappings are possible and there can be multiple
transformations involving different attributes/columns between two entities/tables as illustrated below.
TIP: Displaying the transformation definition, inputs and outputs, and code is controlled by the
Transformation options in the Diagram and Object Display Options editor. For more information,
see Configuring and Customizing ER/Studio.
