How does IMS handle concurrency and locking in database operations?

IMS ensures data integrity and manages concurrency through locking mechanisms. It uses lock points to control access to a particular data item, ensuring that only one transaction can access or modify it at a time. IMS also supports various types of locks such as exclusive locks, update locks, and shared locks to prevent data inconsistencies.

In addition, IMS allows for customizable locking configurations to optimize performance and prevent deadlock situations. By efficiently managing concurrency and locking, IMS ensures that database operations are executed securely and without conflicts.
