ODBC/JDBC solutions suffer from "least-common-denominator" symptom;  one can't
easily exploit Oracleisms.  I haven't played with DCOracle yet, but wrapping OCI
into a nice Pythonic package would be a big win in some situations (passing
array parameters to stored procedures is the one I most often want).
