9/24    Has anyone used an ORDBMS? Is it very different than an RDBMS? Are
        there free ORDBMS out there to play around with? I'm trying to map
        a lot of structured, hierarchical XML to mySQL's RDBMS schema, and
        it is pretty adhoc and ugly.
        \_ If you don't need to query based on the details but only store and
           retrieve the structure, you might think about just serializing the
           contents and storing that in a blob, accompanied by columns with
           whatever keys you _do_ need.  It's a real time-saver.
           \_ I have over 1 GIG of data and need to retrieve AVG and stuff.
