Here you go. It's easy with a bit of Category Theory. Just implement something along the lines of David Spivak's "On The Relational Foundations Of Functorial Data Migration". http://arxiv.org/abs/1212.5303 Original motivation, from v1 of the paper: I asked whether the difficulty in changing data types to allow for longer integers was simply a storage issue or something more fundamental. They said that it was more fundamental, and in fact that my question showed how little I knew about the horrors of using databases in the real world!
