You're designing a banking system where customers can transfer funds between accounts. How would you ensure transaction atomicity and consistency in this scenario?

In this scenario, ensuring transaction atomicity and consistency is crucial to maintain data integrity. Utilizing database transactions and ACID (Atomicity, Consistency, Isolation, Durability) properties provides a robust mechanism to ensure that either all operations in a transaction are performed or none are, thus maintaining consistency and atomicity. ACID properties guarantee that even in case of failures, the database remains in a consistent state.
