The road to Utopia: A future for generative programming

Abstract

The future of software engineering lies in automation and will exploit the combined strengths of generative programming, domainspecific languages, and automatic programming. While each of these areas is still in its infancy, a spectacularly successful example of their combination was realized twenty-five years ago: relational query optimization. In this paper, I chart the successes and mindset used by database researchers to generate efficient query processing programs automatically. I argue that the road that they have so successfully followed is the same road that the generative programming, domain-specific languages, and automatic programming communities are now traversing.
