@Johan Vergeer you can have a look here for ORMs
https://github.com/KotlinBy/awesome-kotlin#libraries-frameworks-database
For a full-blown ORM: Exposed is probably more what you are looking for.
But I'm in agreement with
@mp, a full-blown ORM only offers so much, For a micro ORM I had a look at kwery, but then moved over to kotliquery, because I liked kotliquery's implementation better.
