The short version

  • Each has a real cost: Oracle Database high licensing costs for Enterprise Edition with option packs potentially doubling the effective per-processor cost; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: Oracle Database covers PL/SQL, Signal covers End-to-end encryption.
