Description

This lecture covers the concepts of transactions, ACID properties, schedules, and locking protocols in database systems. It explains the definition of transactions, the importance of atomicity, consistency, isolation, and durability. The instructor discusses the execution of transactions in parallel, the role of schedules in database management systems, and examples of interleaving schedules. Additionally, the lecture explores anomalies that can occur with interleaved execution, such as reading uncommitted data and overwriting uncommitted data. Conflict serializable schedules and the use of precedence graphs to determine conflict serializability are also explained.
