Relational Blocks: A Visual Dataflow Language for Relational Web-Applications

Many Web-applications can be characterized as "relational". In this paper we show that developers can greatly benefit from relational blocks, a visual, domain-specific, dataflow language that is designed to facilitate the construction of such web-applications. We define the relational blocks visual language, discuss our WebRB implementation, and show how WebRB is used to construct non-trivial web-pages.
