I would think any patent would have expired by now as Oracle was founded in 1977.

  Yes, but it wasn't what it is now. First version programmed in C (not assembler) was version 3 (1983). Row-level locking was introduced in version 6 (1988). Constraints, stored procedures and triggers - version 7 (1992).

    Oracle didn’t have transactions until 5 or 6 if I remember correctly
    • snaky 9y ago
      AFAIR transactions were implemented in Version 3.

        Just checked the manual and we were both wrong - version 4
        • snaky 9y ago
          Ah, and version 4 was rewritten in K&R C! (from White Smith C)
