I can only answer from a perspective of data persistence. DataNucleus provides (at least) as many features as Hibernate for persistence to RDBMS, and SQL, and is fully compliant with *all* specifications in that domain. Why you think that you gain something by having Hibernate is unknown to me. The datastore concerned here is simply not an RDBMS so cannot offer some of the things found in RDBMS. There are ample blog postings relating to the differences. Similarly Hibernate has no support for persisting to other types of datastores, so if the datastore is BigTable then how do you expect such support to appear in Hibernate.
In the same way what does SQL do for you that such as JDOQL/JPQL/GQL don't? Some concepts just don't exist in the BigTable datastore. If instead your question was with respect to BigTable against RDBMS then ok, I'd leave that to Google to answer, though obviously there are ample posts in this forum by Google people answering it. --Andy (DataNucleus) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
