A proposed model for developing distributed programs by prototyping

The model for prototyping has three basic elements that can function as independent tools. These three elements are: programming environment, system, and program visualization. The programming environment helps the programmer write high level distributed programs with no more effort than sequential programming. The system element executes distributed programs and records their behaviour in dedicated descriptors that act as the model´s unifying paradigm. Programming visualization lets users monitor program behaviour and rectify problems interactively by program reversion and partial program replacement. Test results show that the model can shorten software development time and enhance software quality by uncovering and rectifying errors quickly
