Hey folks! I've got a question... I'm looking at developing a website that generates its content based on an XML feed from an API call. My question to you is, what's more efficient, constantly making API calls and downloading a lot of information, or saving calls to a database and recalling them when needed?

See, I'm not sure how many requests will be served NOR am I sure how often the API sources will be updated... is there a place where a line gets crossed and says a database would be better than constant API calls?

Thanks,
Jared
