FAQs on Serializability Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)

1. What is serializability in the context of computer science engineering?
Ans. Serializability in computer science engineering refers to the property of a system where transactions occur in a way that their execution appears to be serial (one after the other), even if they are actually executed concurrently.
2. Why is serializability important in database management systems?
Ans. Serializability is important in database management systems to ensure that transactions are executed in a manner that maintains data consistency and integrity, preventing conflicts and ensuring that the final state of the database is correct.
3. How is serializability different from other forms of concurrency control in databases?
Ans. Serializability differs from other forms of concurrency control, such as locking and timestamp ordering, in that it focuses on ensuring that transactions are executed in a way that maintains consistency, rather than just preventing conflicts.
4. What are the common algorithms used to achieve serializability in databases?
Ans. Common algorithms used to achieve serializability in databases include Strict Two-Phase Locking (2PL), Serializable Snapshot Isolation (SSI), and Serializable Linearizability.
5. How can serializability be implemented in distributed systems?
Ans. Serializability can be implemented in distributed systems through techniques like distributed locking, distributed transactions, and coordination protocols such as Two-Phase Commit (2PC) and Three-Phase Commit (3PC) to ensure that transactions maintain serializability across multiple nodes.
