What do you understand by dirty read in terms of database?

Dirty reads occur when a transaction is allowed to read a row that was modified by another transaction that has not yet committed. Non-commit readings work the same as non-repeatable readings; However, the second transaction does not need to commit for the first query to return different data. The only thing that can be prevented in the isolation level "Readings without commit" is that the updates appear out of order.
