Well, I don’t have much to say about the Refactoring: Change Bidirectional Association to Unidirectional (which is what I decided to look at this week on Monday). Sounds great! Change it if it makes sense.

Like Fowler says in the book, “The most difficult part of this refactoring is checking that I can do it.”

If the change will not cause too many ripple effects, it can be done very nicely. Otherwise, you may be facing a big ball of mud and it may not be feasible.
