Concurrency management is a problem for distributed database systems too. Do unmodified systems need concurrency control mechanisms like 2PL (Two-phase locking)? Explain.

Describe the two-phase locking protocol and its advantages in concurrency control.

It is challenging to handle concurrency in a distributed database, just as it is in other distributed systems. Since there are no copies, may 2PL (two-phase locking) be used? Explain?

Consider a database system for an airline that employs snapshot isolation. Describe a situation in which a non serializable execution happens, but the airline is ready to tolerate it in exchange for improved overall performance.

Discuss the ACID properties and their significance in the context of concurrency control.

How do "spinlocks" differ from traditional locking mechanisms in concurrency control?

What is the concept of deadlock detection and resolution in concurrency control? Describe the various deadlock detection algorithms and their trade-offs.

Distributed database management systems face the same concurrency control challenges as other categories of distributed systems. Is it necessary to employ concurrency control mechanisms such as two-phase locking (also known as 2PL) in a configuration with no duplicates? Explain.

This example might be improved by starting with a database maintained by an airline that employs "snapshot isolation." What if, rather of increasing the airline's overall performance, a non-serializable execution did so?

What strategies might concurrency mechanisms use to avoid a deadlock? Please, no handwritten responses, no single-worded, single-phrased, or single-sentence responses. Please assist me in comprehending it.
