How can I ensure data consistency in my backend development?

To ensure data consistency, you can implement transactions, use database constraints, and apply data validation.

What are transactions, and how do they help with data consistency?

Transactions are a sequence of operations performed as a single logical unit. They help maintain data integrity by ensuring that either all operations succeed or none do.

Can you give me an example of using transactions in a database?

Sure! For instance, in a banking application, transferring money from one account to another should deduct from one account and add to another in a single transaction.

What are some common pitfalls to avoid when ensuring data consistency?

Common pitfalls include neglecting to handle errors during transactions, not using proper isolation levels, and failing to validate data before processing.
