[Koha] Integration points with Organisational ERP

Dear Koha Community I would like to hear from university libraries using KOHA, on integration points they have achieved with the university-wide student/finance system with KOHA. e.g. When a student is registered on university ERP, a trigger creates or updates a matching record on Koha. When an order encumbers funds on koha, a trigger does the same on university's finance system. We have just been asked by our programming team what integration points we need and could only think of a few. Any integration experience outside a university system is welcome as well. Thank you Regards /Bravismore
