    Ahmed,

    Nobody argues with your general points. Please try to understand what
    people say before posting another manifesto.

    All I was implying is that ORM, being based on the object identity
    concept, can't cleanly represent the report data that generally has
    no notion of identity and therefore - no relationships. Does it mean
    you can't convert such data to objects? No, you can (and in fact
    Cayenne does that). Can we do it better? Sure. Will this still be
    "object RELATIONAL mapping"? I say no, even though any solution would
    take advantage of Cayenne access stack and some metadata.
