A few years ago I had the pleasure of developing with Oracle Application Express, a lovely 4GL I learned to appreciate for its convenience and ease of use. A search on a different Oracle issue brought me to a lovely video series by Jennifer Kreie, teaching the fundamentals of APEX 5, which may be of benefit to anyone wishing to make the first steps with this useful tool.
