Question

A schedule in which uncommitted transactions that read an item from a failed transaction must be ________.

Answer 1

Uncommitted transactions that read from a failed transaction must be aborted to maintain data integrity and adhere to atomicity and isolation properties in transaction processing systems.

Step-by-step explanation:

A schedule in which uncommitted transactions that read an item from a failed transaction must be aborted.

This is to ensure that any operations that depend on the uncommitted or failed transaction do not propagate potential errors throughout the system.

In database systems, maintaining data integrity is crucial and one of the practices to enforce this is to use transaction logs and abort transactions that might have read 'dirty' data.

This concept falls under the subject of transaction management and is part of ensuring atomicity and isolation properties in a transaction processing system.
