SQL and I use it with Oracles Application Express to create webapps for my company to streamline efficiency, secure data and reduce costs.
I've came a across some APEX applications but I've never actually had the chance to see how they are written. So you actually write a web application in SQL?
(Stolen from Oracle's website).
For example: I'm using PL/SQL in my latest app to send both scheduled emails and SMS to customers, if they meet certain criteria, within our database by combining several tables that compartmentalise data, without exposing it to the world, using PL/SQL and RESTful services. It's insane. And that's only taken me a few weeks to create (considering I'd never heard of RESTful services until then).
We’re a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
