An example of an AI chatbot conversation about dirty reads in database transactions.
Can you explain what a dirty read is in database transactions?
A dirty read occurs when a transaction reads data that has been modified by another ongoing transaction but not yet committed.
Why is it called a dirty read?
It's called a dirty read because the data being read may be 'dirty' or inconsistent, as it could change if the other transaction is rolled back.
What are the implications of allowing dirty reads?
Allowing dirty reads can lead to inconsistencies and unreliable data, which may affect decision-making based on that data.
How can we prevent dirty reads?
Dirty reads can be prevented by using isolation levels like 'Read Committed', which ensures that only committed data is read.
