I'll take the chance to do a little advertising. Our ORDBMS (see my sig) provides an
in-memory mode, however disk storage is still involved for persistence. We also provide
something we call 'flash' mode which is in-memory mode without persistence, no data on
disk at all. All data is completely transient. It has transactions though in memory, so
it is very fast. It's implemented in Java, but we have an ODBC driver.
