RASD (Rapid Application Service Development) development platform for fast createing web based applications with less or no programming.
For developing in RASD all you need is browser. The program you create is published as HTML5 or REST service. All subprograms (look up's, ...) are published as HTML5 or. REST too. If you create batch program in PL/SQL you can use the same tool. All generated by RASD can be overwritten with using triggers (remember classical Forms).
