Abstract: A Formal Approach to Domain-Oriented Software Design Environments

Michael Lowry, Andrew Philpot, Thomas Pressburger, and Ian Underwood

This paper describes a formal approach to domain-oriented software design environments, based on declarative domain theories, formal specifications, and deductive program synthesis. A declarative domain theory defines the semantics of a domain-oriented specification language and its relationship to implementation-level subroutines. For mal specification development and reuse is made accessible to users through an intuitive graphical interface that guides them in creating diagrams denoting formal specifications. Deductive program synthesis ensures that specifications are correctly implemented. This approach has been implemented in Amphion, a generic KBSE system that targets scientific subroutine libraries. Amphion has been applied to the domain of solar system kinematics. Amphion enables space scientists to develop, modify, and reuse specifications an order of magnitude more rapidly than manual program development. Program synthesis is efficient and completely automatic.
