In this lecture, I explain the core concepts of Distributed Transaction Processing, based on Chapter 5 from Principles of Distributed Database Systems by Özsu and Valduriez.
We explore how database systems maintain consistency, reliability, and isolation when multiple users or systems access data concurrently in a distributed environment.

🔍 Topics Covered:

Concept of Transactions: The basic unit of consistent and reliable computation in database systems.
Reliability and Recovery: How distributed systems handle failures and ensure durability of committed transactions.
ACID Properties: Atomicity, Consistency, Isolation, and Durability explained with examples.
Distributed Architecture: The roles of Transaction Manager (TM), Scheduler (SC), and Local Recovery Manager (LRM).
Transaction Commands: Begin, Read, Write, Commit, and Abort — and how they function in a distributed setting.
Concurrency Control: Serializability, isolation levels, and global transaction management.
Commit and Abort Protocols: Ensuring data integrity across multiple sites.

💡 Through this video, you’ll gain a clear understanding of how distributed databases coordinate concurrent transactions, maintain data consistency, and recover from failures efficiently.
