Can you explain what a dirty read is in SQL?
A dirty read occurs when a transaction reads data that has been modified by another transaction but not yet committed.
Why is it called a dirty read?
It's called a dirty read because the data being read may not be reliable or consistent, as it could change before the transaction is committed.
What are the implications of using dirty reads?
Using dirty reads can lead to inconsistencies and errors in your application, as you might be working with uncommitted data.

You can avoid dirty reads by using appropriate isolation levels, such as 'READ COMMITTED', which only allows reading committed data.
