Plugins to add custom database table and pull reports

I’m looking for a way to store information in a database table and be able to recall it for editing or display. Example: I will have a list of vendors, each of which has separate fields for phone, type of business, etcetera. I need to be able to set up several of these custom tables, and have pages / space to edit the content as well as display the results.

Anybody have any clues on where to start? Thanks!
