VHLL (Very High Level Language) System Prototyping Tool

This report contains the results of studying issues relating to the requirements development process. The goals, objectives, results and conclusions for three separate but related components, 1 a Requirements Engineering Panel study, 2 the development of a Very High Level Language Prototyping Tool, and 3 a Database Management Study are described. First, a panel of experts was formed whose goals were to understand the requirements engineering problem and define a long-range 10 year Research and Development plan for the RADC Requirements Engineering Testbed RET. The plan was to identify tools and methods that should be developed, evaluated and integrated. Second, the objective of the rapid prototyping system, Proto, was to develop a functional specification, prior to extensive design and coding effort in a large C3I software system. The approach includes defining a functional specification language for defining prototypes, developing and organizing a facility around the concept of reusability with the reusable components both functions and data types managed by an object manager, and develop a set of support tools to facilitate the construction and execution of prototypes. Finally, a study was performed to identify the data base management requirements for supporting an automated requirements engineering process.
