In the previous post I wrote that I didn’t quite like drag-and-drop development style in JDeveloper that I experienced during Oracle OpenWorld hands-on session.
Today I was in Oracle BI Answers & Dashboard hands-on session and during this session I was also drag-and-dropping to create reports, charts and business intelligence dashboards. But in this case I liked it as it seemed natural way how to create such reports.
The main difference why I liked it was that I got immediate feedback how the end report will look like – after each change I could immediately see and test real report with real data. And such immediate feedback is key prerequisite for interactive analytical reporting development.
In JDeveloper case I needed to compile and build everything and restart local application server after each change to see real results from any change – and it took at least 10 seconds for just sample “hello world” application. I assume that this lag will be even longer in larger real projects. Probably it is not so long time but when you compare it to 1 second feedback time then anything larger seems long.
