When I was working at Wang Trading, I was using external tables to load the external data. Bloomberg files were coming in on nightly basis, I would map them to an external table and load (pre-processed) data into the database. PQO was used, so the whole thing was reasonably fast. External tables are user-friendly SQL loader, not much to talk about it.
