I don’t think it’s true that most of the original OODB systems didn’t
support query optimization or transactions. It depends a bit on what
you mean by “original”, but if you mean the generation of companies
that appeared in 1988, I don’t think it’s true. ObjectStore
absolutely always supported ACID transactions. It also had a query
optimizer, albeit a simple one, without any impendence mismatch.

You say that relational data maps fairly well to objects, but there
are a lot of big problems, which have been written about at great
length. For example, it is difficult to model inheritance in
relational databases. This is not a “fine point”; it’s crucial.
