  1. Database structure by app type in Bubble manual
  2. YouTube videos (free)
  3. Bubble coaches from here: Coaching | Bubble
  4. There is a bunch of projects dedicated to Bubble education, including database structuring (not sure if it’s allowed to mention them here), but you can google’em with ease

P.S. Also there are some “how-to” blog posts in Bubbles blog: How To Build Any App With No Code - Bubble

I’m no bubble pro, but, as a software engineer, I can tell that there is no such thing. It depends on your needs. If you have a specific project, it’s better to ask someone (and pay them for their time).
