Using persistence technology to control schema evolution

The content of these chapters derives from two papers which explore further the possibilities of the hyperprogramming and hypercode concept. Neither paper describes engineered systems, but rather both are workshop papers which explore long-range possibilities of systems built around the hyperprogramming model. Although most FIDE research is based upon engineering practice as well as ideas, these papers are purely conjectural; the hyperprogramming and hypercode systems are built and in use, but a second generation of such systems is a prerequisite before the engineering aspects of systems such as those outlined here can be investigated, and so at the time of writing these remain descriptions of potential research projects.
