What is database transaction consistency?
Database transaction consistency ensures that a database remains in a valid state before and after a transaction.
Can you explain how it works in a relational database?
In relational databases, consistency is part of the ACID properties, ensuring that all transactions bring the database from one valid state to another.
What happens if a transaction violates consistency?
If a transaction violates consistency, it may lead to data corruption or invalid data being stored, which can cause errors in future transactions.
How can we ensure consistency in distributed databases?
In distributed databases, consistency can be ensured through protocols like Two-Phase Commit or using eventual consistency models.
