Why is consistency important in databases?

Consistency ensures that all database transactions are reliable and that data remains accurate across all instances.

Can you give me an example of a consistency issue?

Sure! Imagine a banking system where a user transfers money. If the database isn't consistent, the money might be deducted from one account but not added to another.

What are the different types of consistency models?

There are several models, including strong consistency, eventual consistency, and causal consistency, each with its own use cases.

How does consistency affect database performance?

Maintaining consistency can impact performance, as it may require additional checks and balances, potentially slowing down transactions.

What strategies can be used to ensure consistency?

Common strategies include using transactions, locking mechanisms, and replication to ensure that all data remains consistent.
