  3. SQL transactions: every participating call uses the transaction

    Place an atomic business transition inside one explicit transaction owner.

    3 min · Worked lesson

  4. SQL isolation and deadlocks: test the business invariant

    Explain why atomic statements alone may not preserve a multi-row invariant.
