i am trying to create a report that would show how the column (column_name) in a database schema were derived using Talend. thus if table ATTENDANCES - att_dt datetime - pat_id int - att_type int - total_cost float there are two jobs in Talend that populate this table. now we may need to change the legacy source system. and i would like to be able to know what will be the objects (tables) that will be impacted. but also to know where a data source (table) is used? does it clarify?
