I recently was duped (by myself) at a discussion with a colleague: in our continuous effort to disentangle release schedules of two tightly entangled applications, I exposed some core features as a JSON REST service and told him to "just use the Spring invoker" for JSON.

Business keys are entity properties which … Continue reading On JPA identifiers and business keys (or why business keys are a bad idea)
