Hi
There are so many questions in my mind right now about all this thing ... Where do you get the file/feed/zip from and what's its format, could you please provide a sample such file ? Do you already have a database structured and organized where all that data needs to go into ? Is it also included in the project the creation of that page you attached in the screenshot ? Will you be able to set up cron jobs on your server for the regular updates that will need running that script ? How large the downloaded file usually is (how many records, approximately, if you happen to know) ? Huh, that's it for the moment, please take your time :)
