Describe the two-phase commit (2PC) protocol in distributed database management. What are the steps involved in 2PC, and how does it ensure atomicity of transactions in a distributed environment

Describe the concept of distributed transactions in a DDBMS. How does the Two-Phase Commit (2PC) protocol ensure the consistency of distributed transactions?

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.

Explain the two-phase commit protocol and its importance in distributed database transactions.

Examine the challenges and solutions associated with fault tolerance and recovery in distributed database systems. How can data be recovered after a failure in a distributed environment?

How does the Two-Phase Commit (2PC) protocol work in a distributed database system, and what are its limitations?

Discuss the two-phase commit protocol and its role in ensuring distributed database consistency.

Discuss the ACID properties (Atomicity, Consistency, Isolation, Durability) in the context of distributed transactions. How are these properties maintained in a distributed environment?

Discuss two-phase commit (2PC) and three-phase commit (3PC) protocols in the context of distributed transactions. How do they ensure data consistency?

What are the challenges and strategies for achieving fault tolerance in distributed database systems? How do distributed consensus algorithms like Paxos and Raft contribute to fault tolerance?
