Visual programming as an interface between program and user?
S. Dahl, K. Lindqvist · 2003
Visual programming ought to mean programming by gestures and image manipulation where the computer manufactures the executable code, rather than forcing the user to learn just another programming language where, for example, the Pascal notation is replaced by flow diagram symbols. Instead the authors define, as an example, a simple visual notation for querying databases via images, where the manipulation of the images and the gestures performed by the user generate SQL-code that can be executed by any database manager based on SQL.>
