Abstract: The present consideration of the observational constraints and theoretical components required for computing the Galaxy's chemical evolution gives attention to the interpretation of abundance patterns observed in stars in the solar vicinity as tracers of such evolution, and presents examples of chemical-evolution model constraints for stellar evolution theories. The specific evolutionary model presented indicates that observed abundance patterns are well reproduced by taking the different roles of Type I and Type II SNs into account in galactic enrichment; the former contribute about 70 percent of the Fe in the Galaxy.
