Understanding Dirty Reads: A Database Isolation Problem
What is a Dirty Read?
A dirty read occurs when a transaction reads data that has been written by another transaction but not yet committed. If the writing transaction rolls back, the data read by the first transaction becomes invalid—hence, "dirty."
This can lead to inconsistent or incorrect results in applications, especially in systems where multiple users or processes are accessing and modifying the data concurrently.
