Can you explain how isolation impacts atomicity and consistency in database transactions?
Sure! Isolation ensures that transactions are executed independently, which helps maintain atomicity and consistency.
What happens if isolation is not properly implemented?
Without proper isolation, transactions can interfere with each other, leading to issues like dirty reads and lost updates.
Can you give an example of a problem caused by lack of isolation?
Absolutely! A classic example is the lost update problem, where two transactions read the same data and then overwrite each other's changes.
How do different isolation levels affect these issues?
Different isolation levels, like Read Committed or Serializable, balance performance and data integrity, affecting how transactions interact.
