1) They belong to ____
2) They operate on ____
3) At least one of the two operations is ____

Answer 1

In the context of databases or operating systems, two operations in a schedule conflict if they belong to different transactions or processes, operate on the same data item or resource, and at least one is a write operation.

Step-by-step explanation:

Understanding Schedule Conflicts in Operations

When managing schedules, particularly in the context of databases or operating systems, two operations in a schedule may conflict under certain conditions. Specifically, a conflict arises if:

1. They belong to different transactions or processes.
2. They operate on the same data item or resource.
3. At least one of the two operations is a write operation.

This concept is important for ensuring data consistency and preventing deadlocks in systems that require concurrent data access. In scheduling terms, conflict serializability is a concept used to ensure that a schedule for executing database operations will result in the same state as if the transactions were executed serially, without overlapping in time.
