Locking modes pessimistic locking: Lock before accessing an object
Optimistic locking: Read and writes can freely occur (high degree of concurrency).
Administration: Modern DBMS requires specially trained staff to set up security policies, prepare backups, manage the disk space, monitor performance and fine-tune the performance.
