And guess where the Ruby language is implemented? And for a more-or-less
coherent API similar to JDBC or ODBC, you'd have to dig a bit into Ruby.
Not a lot, I guess, but still a bit.

Similar != equivalent. And Ruby::DBI isn't all that agnostic in regard
to databases, since you still have to use SQL (which is true with JDBC,
too, I know). However, JDBC massages SQL a bit, to enable a somewhat
seamless integration of databases in applications.

Similar to what ORM libraries offer for Ruby. You can expect to get the
same type of result out of an ORM, similar to JDBC.

While Ruby::DBI needs a bit of fine tuning in that area. That might be
different in newer releases than the one I looked at and used (that was,
what, a year and a half ago?).
