Which is an architectural model in parallel database architectures?Question 5Select one:a.Shared everythingb.Shared somethingc.Shared nothingd.Shared bytee.Shared power plug

The architectural models in parallel database architectures include:

a. Shared everything b. Shared nothing

These models describe how resources like memory, disk storage, and processing units are shared among the processors in the system.

a. Shared everything: In this model, all the processors share the same memory and disk storage. It's easy to implement but can lead to contention when many processors try to access the same resource.

b. Shared nothing: In this model, each processor has its own private memory and disk storage. This eliminates contention but can make it harder to balance the load evenly across processors.

So, the answer to your question is either a. Shared everything or c. Shared nothing.
