I made https://github.com/JuliaData/Strapping.jl, which is part of an ORM; i.e. it does the translating between Julia objects/vectors of objects and 2D tables. But it doesn't do some of the more "magical" things like SQL generation, automatic migrations, etc.

I think it'd be cool to do some of the SQL generation stuff, but no one has sat down to design something out and how it would work in Julia.
