We propose to extend the idea of Adaptive Programming to enable full scale development of real life software. We propose to conduct research in three parallel directions as follows. Extending existing tools. Extending the known algorithms, we would like to develop practical tools which will ....

....In our test cases, an order of magnitude reduction of size is typical. The current implementation of Adaptive Programming has proved remarkably successful. It has been used to successfully manage the evolution of its own implementation [56] and for modeling 8 business processes in a bank system [24, 25]. Both of these applications involved considerable evolution in their underlying data structures, and the polymorphism in our adaptive programs significantly decreased the amount of recoding necessary as these systems evolved. F.2 Key Research Activities The goal of the proposed project is to ....

....0 . In the following sections, the impact of primitive class transformations on the regression testing process is analyzed. Previous studies have identified the maintenance effort required to maintain object oriented programs during class evolution versus that of maintaining propagation patterns [4, 9, 11]. 4.1 Object Preserving Class Transformations The object preserving class transformations proposed by Bergstein [3] are based on maintaining the structural consistency of objects in a database while optimizing the class design. Two class graphs are objectequivalent if they define the same set of ....

They provide a necessary level of abstraction when implementing object behavior to facilitate class evolution [3] [5]. A propagation pattern implements an algorithm based on a generic class structure, and can be customized with specific class structures in many programs. A propagation pattern consists of a signature, traversal directive, transportation patterns, and code fragments. A Signature specifies the ....
