Seems pretty nice to me. Like a light weight version of the Django's
migrate and queryset features which build on model definitions.
It seems like this would allow me to define a database schema (tables,
relations and fields) as data and use it to both create the database and
run select/insert/update/delete queries against it.
Is that your intention for the library?
I've not explored the options in this space before. It might be good to
have a section in the README pointing out to other related tools with some
compare/contrast points.
Thanks.
