Automated data gathering (collate information from different websites) a few SQL queries

Script/program to : Set up a database based on available data on a master website Gather data from several other websites (approx 5) to enrich the master data. Set up a few basic queries available on web browser Need to be able to add more queries myself easily I understand that if the current websites change the automated polling of data may not work anymore.. You understand i might need to add other websites in the near future so maybe a follow-up project is possible if all goes well. Everything should be able to run under a basic [login to view URL] account hosting. If data exceeds the 10G hosting we need to figure out some archiving weekly automated. (phase2?)
