Since when did Oracle win in databases? Mr Mueller may think so as a consultant but in my almost three decades as a developer I have never worked on an Oracle database, have never been asked to work on an Oracle database and the last time a customer mentioned Oracle to me would have been about 20 years ago. Oracle, like DB2, is a ghost from a bygone era.
If he had said PostgreSQL had won in databases I'd have agreed with him but Oracle? Funniest thing I've heard so far today.
