I think the main problem is that you haven't stated your ex-
perience with SQL (or databases in general). Your questions
above ("somehow connect to the generic table", "go about
querying those tables") indicate that you seem to be lacking
basic knowledge. In this case, it won't help you, us or your
database to ask how to structure your data; you should read
a tutorial, and then choose a structure that you understand
and that works for you.
But at the moment, you're basically saying: "I'd like to
build a vehicle; I haven't decided yet whether it should
take me to the next pub or the moon. Which screws should I
use?"
