OK, so in a twist of direction, I thought I'd share my thoughts on HTMLDB.
I've been working with it for a couple of months now I guess. I have to tell you that this is a great environment to develop in. I have really enjoyed the experience. It's a solid product, and the Oracle HTMLDB forum is just remarkable. The actually HTMLDB developers are there... often your question has already been asked and answered on the forum, and the answer is from one of the developers themselves!
I won't say that HTMLDB is simple, certainly basic development is easy. Like anything else, complexity and logic requirements can add to the HTMLDB learning curve. Still, I'd say in spite of this, the learning curve is frequently not as steep as it might be with other languages.
My plan is to start learning more java script so I can integrate that into my HTMLDB screens... but for now, I'm covered up with design paperwork.... so maybe in the future I'll be able to get to it.
So, if you are looking at needing to do some web development, look into HTMLDB.
