    I am all for having some sort of "synchronize" feature in addition to
    "drop/create" and "reverse-engineer".

    However database support of what can be done via "ALTER TABLE ..." varies
    greatly by the vendor. And there is also plenty of cases that can't be
    handled by the modeler at all. Some DDL changes require writing SQL
    scripts manually to migrate the data intelligently, and can't be expressed
    as a simple "delta" between the current state of the database and the new
    state of the model. But then, having a Modeler-generated script containing
    all ALTER TABLE statements can be a good start to do further manual

    Actualy my personal vote would be to begin with implementing "synchronize
    DataMap" for the cases when the database is updated by some external tool
    or by DBA. But of course this depends on how you project process i
