Question

Testing for conflict serializability: Algorithm 21.1: Looks at only ___ and ____ operations?

1) Read
2) Write
3) Commit
4) Abort

Answer 1

Algorithm 21.1 for testing conflict serializability in databases focuses on read-and-write operations to check for conflicts in transaction schedules. Commit and Abort are related to transaction state and outcome and are not involved in this analysis.

Step-by-step explanation:

When testing for conflict serializability in transaction schedules, Algorithm 21.1 considers primarily two types of operations: read and write. This is because these operations can lead to conflicts when transactions are trying to access and manipulate the same data concurrently. Commit and Abort operations are more about the state or outcome of the transaction, rather than the concurrent access and manipulation of data, which is why they are not considered in conflict serializability analysis.
