Statement Analysis

The "wait-die" scheme is a method used in database management systems to handle deadlocks when multiple transactions are competing for resources. In this scheme, a young transaction waits for an older transaction to release a lock. If the older transaction is waiting for a resource held by the younger transaction, the older transaction "dies."

Non-Preemptive Techniques

A non-preemptive scheduling technique means that processes are not forcibly suspended; instead, they run until they finish or voluntarily yield control.

Evaluation

1. In the wait-die scheme, a younger transaction will wait but does not take control of resources from an older one—this aligns with non-preemptive behavior.
2. There’s no forced termination or preemption of the older transaction.

Conclusion

Based on the definition and functioning of the wait-die scheme, it can be categorized as a non-preemptive technique.

Final Answer

True: The wait-die scheme is a non-preemptive technique.
