a newbie question about a database getting updated from the web

[hartmut]

Hello

This is way out of my league, I am a mac guy and very little experience. But I would like to write a database/ which somehow could get upgraded from the web. I would like to make a script within the database that could summon the internet and somehow upgrade ( add or delete records from the local database. Is this possible . Are there examples or training for this type of thing?

Thanks

Dave
