I'm pleased to announce an open-source mini-project that I have been working on to make ORM relationships easier to view. Its called bear.
bear takes metadata from ColdFusion ORM entities and turns it into a readable text-based diagram of the relationships and properties.
How it works
bear runs as its own application and uses ColdFusion mappings to read entities and their information. Provide all the mappings that your application uses for entities
How to make it work
Download the code somewhere local. Run.
