Ask HN: What are some examples of good database schema designs? | Hacker News

I've seen many examples of database schemas but don't always recognise a good design over a mediocre or poor design.This is what I mean by schema (is this a good design?) https://www.drupal.org/node/1785994 When I read about database schemas with thousands of tables I wonder what kind of problem could possibly require so many tables. What are good schema examples? And what are some poor examples?
