Upstream -> ETL -> Downstream.

ETL : Extract , Transform and Load. In current context, ETL is done through Data Stage application.

Downstream : This refers to all the applications/processes which are going to consume the output of ETL.

Upstream:  This refers to all the applications/processes which feed the data to be consumed by ETL.

We can interpret Upstream as some thing flowing up like extracting data from source systems(similarly like extracting water from well) and downstream as data flowing into (like water flowing into canal).
