Overview
This pattern is to be used in cases where a previous implementation has a one to one relationship and it needs to be modified to a one to many relationship. This pattern is specifically designed for Objects; however it may be used for lower or higher level concepts.
The Problem
During initial coding/design, you failed to notice that a relationship had the potential to be one-to-many and instead coded it as one-to-one. Now, you realise your problem and need to solve it.
