Am thinking I could loop over the nested hash / arrays myself and attach / convert ActiveRecord objects to the elements or create an appropriate subclass. Then all I’d need to do is call save() if it has_changed() or preferably mass updating them using a temporary table.

It’ll be general enough to act as a general solution for my project at least. Just surprised I cannot find this implemented already for such unstructured and non-formal data mapped onto RDBMS.

Something akin to bdb or Tokyo Cabinet, but on ActiveRecord / Ruby steroids of course.

Maybe associative array activerecord will show more hits. Maybe what I’m looking for is really Hibernate, or some kind of ORM, but I’m having a hard time finding it for sure.

Use Case: For persistence of objects with minimal reads (cache) and writes (partly serializes)

More searching..

Of course ORM gives alot of results, now for some serious reading..

Even more..

Invented before: nosql, schemaless data and document dbs or whatever it was called. Neat concepts and I should be able to be find some wheel, like friendly or similar to that.
