DBMS transaction management. You should also be considering the role your servers play in DBMS transaction management. In general, application performance metrics and user experience metrics provide front-end insight into whether your DBMS server is functioning efficiently. By tracking these metrics, you...
Concurrency: The DBMS also manages concurrency, which means it allows multiple users to access and modify the data simultaneously without compromising data integrity. Backup and Recovery: Another crucial function of a DBMS is managing backups and recovery. It ensures that the data can be recovered ...
Most DBMSs includeindexing modulesto speed up query execution by reducing the amount of data that needs to be scanned. Locking The lock manager component of a DBMS is responsible for managing concurrency control. It prevents conflicts and maintains data consistency by ensuring that multiple users or...
