When it comes to DDD, I highly recommend the book Domain Modeling Made Functional and the lectures the author has given based on the book: https://www.youtube.com/watch?v=9QlhkQl0DSw https://www.youtube.com/watch?v=9QlhkQl0DSw Those two resources where the ones the led to really get and appreciate DDD. One thing I really liked about them is that all the examples are in F# (the functional part of the title) and so manages to make it clear how DDD and OOP are decoupled and how DDD doesn't necessarily imply OOP.
