Samenvatting

6 modellen 27 velden 6 relaties

Een klassiek blog-datamodel: auteurs schrijven posts, ordenen ze in categorieën, koppelen tags via een join-tabel, en lezers laten comments achter.

  • User is de auteur (en commenter).
  • Post hoort bij één User en optioneel één Category.
  • Tag is many-to-many met Post via PostTag.
  • Comment verwijst naar zowel Post als User.
