d language very powerful, but unfortunately, at present is missing a

There is DDBI, but I don't know if this is what you are looking for.

the ddbi progress is too really slow, difficult to look forward toĄŁ
data nucleus is more high-level like Hibernate.
...and this high-level design is IMHO mistake. Especially mapping
relations from db to objects.
I must agree with you. That kind of mapping is nice until you realize
some specific operation must really be super fast, and the only way to
do that is with a custom, super specific query... and then you start
breaking all that abstractions, and everything results in a mess. Pure
SQL, abstracted by convenient methods, is what I prefer. These methods
may return objects that represent entities.
