A fourth choice is using a already written DB package.
Oracle, Watcom, Informix, Progress, M-SQL, DB2, YOODA, Texas
persitant store, etc.
If you're using JDBC you should be able to connect to a number of
pre-existing DBs and mix and match til you get one that performs the

at TDBM though I would need to rewrite the translation layer to fake
ODBC-compliance.
