That's right - Oracle HTML DB has officially been renamed to Oracle Application Express . You still don't need Oracle Application Server, and it has nothing to do with Oracle Express or Express Objects, but it does coincide with the name of Oracle Express Edition Database. This renaming campaign came up once every few months or so when I was at Oracle, as we could never quite come to a consensus on what it should be renamed to. Looks like somoene finally made the call! My only fear with this new name is that people will associate Application with Oracle Application Server, as in it's a required component (as I said before, it still isn't) and Express with "small and insignificant", which is clearly not the limitations of HTML DB - umm, Application Express. It's going to take some getting used to...
Mostly Oracle APEX. Mostly.
