Final answer:
Two schedules are conflict-serializable when they maintain the order of conflicting operations from different transactions. Conflict-serializability is essential for ensuring the correctness of a parallel execution of transactions in databases.
Step-by-step explanation:
Two schedules are said to be conflict-serializable if the order of any two conflicting operations is the same in both schedules. Conflict-serializability is a property in concurrency control in databases that ensures the correctness of a schedule in terms of the serializability of transactions.
To determine conflict-serializability, one must analyze the interactions among transactions, ensuring that non-commutative, or conflicting, operations are not reordered when transactions are interleaved.
A conflict occurs when two operations, from different transactions, access the same object (such as a database record), and at least one of those operations is a write.
If a schedule is conflict-serializable, it is equivalent to some serial schedule, which means the result of executing the transactions in parallel (in the given order) would be the same as if the transactions were executed one after another without any overlap.
