Can you explain what consistency means in the context of database transactions?
Consistency in database transactions ensures that a transaction brings the database from one valid state to another, maintaining all predefined rules.
What are some examples of consistency rules?
Examples include constraints like primary keys, foreign keys, and unique constraints that enforce data integrity.
How does consistency relate to ACID properties?
Consistency is one of the ACID properties, which stands for Atomicity, Consistency, Isolation, and Durability, ensuring reliable transactions.
What happens if a transaction violates consistency?
If a transaction violates consistency, it may lead to data corruption or invalid states, which can cause errors in applications.
