FAQs on Conflict Serializability Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. What is conflict serializability in the context of computer science engineering? |  |
Ans. Conflict serializability in computer science engineering refers to the property of a schedule of transactions in a database system where all conflicting operations are executed in a serial order, ensuring that the final outcome is equivalent to that of a serial execution.
| 2. How is conflict serializability different from view serializability? | |
Ans. Conflict serializability focuses on the order of conflicting operations in a schedule, while view serializability considers the final outcome of the transactions regardless of the order of non-conflicting operations. In conflict serializability, only conflicting operations need to be in a specific order for equivalence, whereas view serializability looks at the overall outcome of transactions.
| 3. What are some common techniques used to ensure conflict serializability in database systems? | |
Ans. Some common techniques used to ensure conflict serializability in database systems include strict two-phase locking, timestamp ordering, and optimistic concurrency control. These techniques help manage concurrent transactions and ensure that conflicting operations are executed in a serializable manner.
| 4. Why is conflict serializability important in database systems? | |
Ans. Conflict serializability is important in database systems because it helps maintain data consistency and integrity by ensuring that transactions are executed in a way that does not lead to anomalies or incorrect results. By enforcing conflict serializability, database systems can prevent data corruption and maintain the ACID properties of transactions.
| 5. How can you detect if a schedule is conflict serializable or not? | |
Ans. One common method to detect if a schedule is conflict serializable is through the use of precedence graphs. By constructing a precedence graph based on the operations of the transactions in the schedule, you can determine if there are any cycles present. If there are no cycles in the precedence graph, then the schedule is conflict serializable.
