Relational databases require locking for concurrent operations to prevent data inconsistency and loss.However, locking impairs how well databases perform. The locking process is often complex.

SQL server deadlocks occur when concurrent processes compete for locks on shared resources.One of the two processes needs to abort and roll back so that the other process can continue.This affects database performance.
