Don't use front-end where it is not required

Regular manual download of data from a portal and loading it into a back-end system is like exiting an airport and then reentering the same airport to catch a connecting flight from the same terminal when you have no business outside the airport. 

I have seen people doing this, downloading data from portals and then loading into other systems manually. If there is no one looking at the data in the UI and no decision is to be made and only regular data feeds are required then don't do it via front-end (GUI), just get a data extract job created that will automatically load the back-end system.
