Description

This lecture covers the fundamental concepts of transactions and concurrency control in database systems. It explains the definition of transactions, the ACID properties (Atomicity, Consistency, Isolation, Durability), schedules, locking protocols like 2PL, and the importance of concurrency for performance. The instructor also discusses anomalies with interleaved execution, aborting transactions, conflict serializable schedules, and concurrency protocols such as two-phase locking. Various examples are provided to illustrate these concepts.
