Some languages do 2 things:
* have a lot of overhead even for rows in a array.
* have connections that default to retrieving all the resultset at once; this is before converting it to the desired storage format.
Perl and PHP would fail this test on both counts; I don't know about Java.
For the sake of testing item 1, above, create a trivial Java program that populates an array of doubles with 1,2,... See how long it takes and see how much memory it takes.
