How do locks work in databases?
An example of an AI chatbot conversation about how locks manage data access in databases.
Can you explain how locks work in databases?
Sure! Locks in databases are mechanisms that prevent multiple transactions from accessing the same data simultaneously.
What types of locks are there?
There are mainly two types of locks: shared locks, which allow multiple transactions to read data, and exclusive locks, which prevent others from accessing the data.
How do locks affect database performance?
Locks can improve data integrity but may also lead to performance issues like deadlocks or reduced concurrency if not managed properly.
Can you give an example of a deadlock?
Certainly! A deadlock occurs when two transactions hold locks that the other needs to proceed, causing both to wait indefinitely.
