A relational programming methodology is developed that enables the rapid design and prototyping of complex, evolutionary software applications, even by non-professionals with minimal supervision. Only relational data structures are used for system content and interface, and programming uses relational languages with an emphasis on relational algebra. The method is successfully applied to the development of two large projects: the Ada Relational Translator experimental compiler-interpreter for Ada and the Multi-Micro Line tool set for constructing multi-microprocessor applications. Cited advantages of the relational programming methodology include: avoiding early commitment to designing data structures and algorithms, extensive facilities for extracting data views when unanticipated functions must be added, and program structuring is decoupled from programming group structure.

Tiny Tim (toolboxes for interactive modeling) is a Smalltalk object-oriented Programming (OOP) language-based collection of toolboxes that facilitates the description, development and programming of complex graphic models and their animation. Tim is part of the Modeller's Workbench, which provides a OOP framework for system simulation and prototyping. Other components of the workbench include the Pose queueing network simulator; Esop, which provides 'expert device during model construction and execution;' and an expert system shell, Stress, which is used in the Tim environment. Smalltalk's OOP metaphor, desktop programming environment, and collections of predefined classes for rapid prototyping of interactive graphical applications is demonstrated through the use of a Tim toolbox for creating a Monte Carlo model for analyzing the 'effectiveness of a batch of lovepotion.'
