Oracle Forms, in my opinion, not too much. I started doing Oracle Forms in 1998, but it had really dropped off by about 10 years later when web became common. There may still be legacy apps running there though, for instance I believe a military business had some very high security data which was viewable only in Forms. For use cases like that often people are slow to re-platform! At one point all the UK natural gas metering went through Oracle Forms, I worked on the original and upgraded systems and around 8 years ago this was still the case.<p>Oracle apex is still used though because if you have an Oracle DB it's such an easy way to build a website over it. It's way easier than Rails or Django, but it can also be enhanced pretty much like a normal web app, it's all restful etc. I know a couple of people who've been working full time on it for decades now,
Curious to understand the reason of not choosing a modern UI and backend using Open Source tech stack such as React/Java/Golang/PostgreSQL ?
