What is a deadlock in database transactions?
A deadlock occurs when two or more transactions are waiting for each other to release locks, causing a standstill.
How can deadlocks be detected in a database?
Deadlocks can be detected using timeout mechanisms or by maintaining a wait-for graph to identify cycles.
What are some strategies to prevent deadlocks?
Strategies include lock ordering, using timeouts, and avoiding long transactions that hold locks for extended periods.
Can you give an example of a deadlock scenario?
