My best elevator description? It's a low code development tool that lives in the browser. Yep, the IDE is a web page that allows you to add SQL, PL/SQL, modify a few attributes - and you've got a data driven web based application that runs on any device. Easy for any Oracle technologist to learn.
This is not a new tool, it's been around since 2004, conceptually even before then.
We've built applications that have lasted for years with minimal inteference. They've outlasted other popular frameworks, and they're still within touch of the present. Still doing the basics of the web, in a clever, interactive way.
AskTom has been using this technology before it was called HTML DB.
It's also being mentioned out there, in the world beyond our bubble.
And it's hitting the news for the right reasons - helping natural disasters.
And helping people take action regarding climate change.
This all started from Kscope19, and it appears momentum continues to grow.
So do you want to board this hardy vessel?
The community is strong & passionate.

Your web page is your IDE now. Lucky, the modern browser is a nifty place to be.
That's APEX. You paste SQL queries / PL/SQL API calls in a box, change some attributes, and there you go. Simples. You have data driven web applications, ready to use on any device.
You know how a web page works? You know Oracle stuff (SQL, stored procedures)? You'll be fine.
If you have Oracle Forms experience, maybe check this out.
Empty the cup.

Install some packaged applications, check out how certain features tick.
Looking for your source code? It is just meta-data in some tables, check out
select * from apex_dictionary;
select * from apex_applications;
See how far the rabbit hole goes.
SQL developer has some dedicated tools for the job.
Try the Maze Runner presentation by Jorge & Jackie, to find your feet.

They have a page titled "How to start as a developer".
Also check out the plug-ins page, to fill any gaps in the builder.
Steady blog stream available here.
Do you like to listen? There are currently two active podcasts.
If you like books, I particularly recommend the collaborative efforts.
If you like videos, I have a series, and plan another. Caleb Curry also has our back.
Need to load spreadsheet data? This. And this.
Want to talk to web services? Find Carsten.
Do you really need to produce a PDF? AOP (APEX Office Print) is your best option.
Moet dingen vertalen? Translate APEX
Want to get a little funky with your page interactions? Check out Maxime's award winning demo app.
I recommend you learn not what you can do for Dynamic Actions, but what dynamic actions can do for you.
Want a second opinion on this list? Try this Github, because it adapts.
Want to get serious about delivering your app? Get a piece of an 'always free' tier, and check out Dimitri's guide. Or you could build you own stack with the free Oracle XE.
Note, the preferred pronounciation is a-pex, not app-ex. I blame my accent for any mispronounciations ;p This guy knows.
It's also "APEX", not "Apex". Possibly as not to be confused with SaleForce 'Apex', which if I recall is something pretending to be Java. "ApEx" is as painful as camelCase.
You generally need to prefix any searches with "oracle apex"
Or just ask a question on Twitter with the hashtag #orclapex. Someone is bound to point you in the right direction.
Note that even those without a Twitter account can browser activity in this tag. I recommend getting involved, it's an active zone for the Oracle team.
You might see it as #orclAPEX, which not only helps get it right, but helps #a11y
Let me know if you think something else belongs here.
