Technology to support system comprehension tends to reflect either a “bottom-up” or “top-down” approach. Bottom-up approaches attempt to derive system models from source code, while top-down approaches attempt to map abstract “domain” concepts to concrete system artifacts. While both approaches have merit in theory, in practice the top-down approach has not yielded scalable, cost-effective tech...
