Having worked with Hibernate for about 5 years i can honestly say that it's
the right solution to the wrong problem.
I think a CQRS-approach with entities in a non-relational store and forking
off statistics/query-data off to a store suitable for data mining is the way
to go.
Basically querying in Hibernate is a mess:
1) Query by example... who uses that?
2) Criteria, a DSL that doesn't even offer type safe queries? WTF?
3) HQL, works good until you realize that you've hit the HQL wall and need
to go with SQL
4) SQL, to the metal, but you get the possibility to retrieve entities with
it ({relation.*}-syntax) gets the job done
Also, there are a lot of quirks and secret ninja techniques you have to be
aware of to get everything to behave like you expect.
I'm not saying it's totally worthless, I'm just saying that I don't believe
in the problem.
