In this article we review the main concepts around database repairs and consistent query answering, with emphasis on tracing back the origin, motivation, and early developments. We also describe some research directions that has spun from those main concepts and the original line of research. We emphasize, in particular, fruitful and recent connections between repairs and causality in databases.
