What is a dirty read in databases?
An example of an AI chatbot conversation about dirty reads in database transactions.
Can you explain what a dirty read is in databases?
Sure! A dirty read occurs when a transaction reads data that has been modified by another transaction that has not yet been committed.
Why is it called a 'dirty' read?
It's called 'dirty' because the data being read may not be reliable or consistent, 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 errors in data processing, as decisions may be made based on uncommitted changes.
How can I prevent dirty reads in my application?
You can prevent dirty reads by using isolation levels like 'Read Committed' or 'Serializable' in your database transactions.
