## Data Lineage
Data Lineage is one of the most powerful features of DI Studio generated ETL. This tool queries it and makes a graphical output to help DI Developers, Data Modellers, and Business Analysts understand the data from both Source to Target and Target to Source.
It is possible to share the URL to any lineage diagram, and export in PNG, SVG and CSV formats. Lineage can be viewed forwards or backwards.
This feature is only available on the SAS 9 version of Data Controller.
