    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).

    Upstream means data channel from source system to ETL.
    there are verity of source system (RDBMS, Flat Files, XML, ODBC).this data is integrated by ETL.this is input to ETL.
    same as upstream.

    Downstream means data generated from ETL.
