Row Locking is a database management technique that prevents multiple users from modifying the same row of data simultaneously. When a user accesses a row for editing, the system locks that row, ensuring that other users cannot make changes until the lock is released. This helps maintain data integrity and prevents conflicts. Row locking is particularly important in environments with high transaction volumes, such as banking or e-commerce systems. By using row locks, databases can manage concurrent access efficiently, allowing users to work on different rows without interfering with each other, thus enhancing overall performance and reliability.
