Final answer:
Two schedules S and S' are view equivalent if they involve the same set of transactions and the same operations of those transactions, leading to the same final state and outputs.
Step-by-step explanation:
Two schedules, S and S', in the context of databases, are said to be view equivalent if the following three conditions hold: The same set of transactions participates in S and S', and S and S' include the same operations of those transactions.
The essential concept behind view equivalence is that both schedules should result in the same outcome from the perspective of the transactions' operations, meaning that they produce the same final state and the same set of outputs from the same set of inputs. This ensures that although the order of operations might differ between the schedules, they are still considered equivalent if they yield consistent results.
