I’ve already seen large scale clojure projects being rewritten to something average devs can maintain. Don’t expect much more growth out of this language in terms of new projects written in clojure.

I'm trying to evaluate clojure for standard enterprise applications. But I haven't seen anything on how to model entities and relations without a database:

   Entities:Person, Insurance, Car
   Relationships:
   Insurance--hasHolder-->Person(m:1)
   Insurance--insures-->Car(1:m)
   Car--hasPrimaryDriver-->Person(1:1)
   Person--drives-->Car(m:n).
   Additional constraint: hasPrimaryDriver(C,P) => drives(P,C).
The domain has cyclic relationships, hence I cannot model it as a tree. If everything is immutable, I have to update all entities that reference each other when replacing one?! What's the standard clojure way to implement it?
