Question

Two operations in a schedule are said to conflict if they satisfy all three of the following conditions: (1) they belong to ___ transactions.

Answer 1

Two operations in a schedule conflict if they are from different transactions, operate on the same data item, and at least one is a write operation. This is crucial for transaction management in databases.

Step-by-step explanation:

In the context of database systems, two operations in a schedule are said to conflict if they satisfy all three of the following conditions:

1. they belong to different transactions,
2. they operate on the same data item,
3. at least one of these operations is a write operation.

Conflict serializability is an important concept in the field of transaction management in database systems. Ensuring that transactions are properly managed in concurrent systems helps to maintain data integrity and consistency.
