If you move Deep to oracle*Forms then its is best Database application Builder available now a days.
So much secure.
Quick and effective database app Developments etc.
A Big step in DATA WAREHOUSING and MINING
I was thinking same as u earlier but now I understood that Forms & reports are the foundation and if you know, it is good for future. Just try to enhance your skills with newer versions and you can get good position.
Forms has a sort of futur in a way that it is still used by thousand clients and will not disapear tomorrow.
But, this is not the tool I will investigate now. Most of the present-day applications runs, now in a Browser, written in half Java and half Dotnet.
I you are really interested in the future, look at the JDeveloper and ADF tools.
