Hi Robert

2 or 3 RDBMS columns can "look like" a Java Collection if you have something like JDO, otherwise it will mostly remain "conceptual".

It seems that you consider SQL as a programming language. For me SQL is well-suited and has been designed for ad-hoc queries outside applications.
JDO QL aim is only to simply identify entry points from which you'll be able to transparently navigate in pure Java. So in JDO queries are less
JDO QL does not pretend to be an ad-hoc query language.

Anyway, a JDO implementation is free to optionally support SQL in addition to JDO QL support. This is exaclty what LiDO, our product does.
