This document is intended to be a guide for performing Extraction, Transformation and Loading (ETL) processes in tranSMART. It covers the ETL pipeline on Windows and Linux systems, for tranSMART instances running on a Postgres database. Chapter one in the Dataset Explorer ETL Guide  gives an excellent discussion on how to plan and build your ontologies, which will determine how data appears in tranSMART. This guide aims to combine the dispersed information on ETL from various sources, such as the tranSMART Foundation Wiki  and the ETL Guide mentioned above.
This guide assumes that you have a working instance of tranSMART installed.
