WebRB: A Different Way to Write Web Applications

Relational Blocks (RBIocks) is a visual dataflow language for writing multipage interactive applications that access, transform, and display relational data in a GUI. The authors present WebRB, an implementation of RBIocks for a Web application environment. It's deployed as a software service; developers run the WebRB visual editor in a standard Firefox Web browser and store their page designs and data on the WebRB server. WebRB is a different way to write Web applications because it uses visual page designs, lacks imperative code, and uses relational semantics.
