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.
### Table Level
Table level lineage shows tables (colour coded per library) and associated jobs (with links to metadata definitions)
Column level lineage shows the transformations and any business logic applied to each variable during the flow. Data items are distinguished between files, database tables, and SAS datasets.
Adding Email Alerts in Data Controller is a case of updating the MPE_ALERTS table (to say which alerts you wish to send) and the MPE_EMAILS table (only if your emails are not stored in metadata)
1 - File uploads. Data Controller will let you upload CSVs (using any common separator) to any target table without having to specify variable formats etc in advance. Changes are routed through the usual approval process with audit trail.
2 SAS File downloads. Other than standard CSV / Excel files, it's possible to download a SAS program containing the data in datalines format. This enables SAS developers to easily work with copies of the data, for testing and development purposes.
