What are the differences between atomicity and consistency in database transactions?
Atomicity ensures that a transaction is all-or-nothing, while consistency ensures that a transaction brings the database from one valid state to another.
Can you give me an example of atomicity in action?
Sure! If a bank transfer involves deducting money from one account and adding it to another, atomicity ensures that both actions occur together or not at all.
How does consistency relate to data integrity?
Consistency is crucial for data integrity as it ensures that any transaction will leave the database in a valid state, adhering to all defined rules.
Are there scenarios where atomicity and consistency might conflict?
Yes, in distributed systems, achieving both can be challenging, as ensuring atomicity may require locking resources, which can affect consistency.
