What are the types of serializability?Transaction serializabilityConceptual serializabilityView serializability

Serializability is a concept in database systems that ensures the concurrent execution of transactions results in a system state that would be obtained if transactions were executed serially, i.e., one after the other. There are three types of serializability:

1. Transaction Serializability: This is the most basic form of serializability. It ensures that the concurrent execution of a set of transactions is equivalent to some serial execution of the same set of transactions.

2. Conceptual Serializability: This is a more relaxed form of serializability. It allows for some interleaving of operations from different transactions, as long as the final result is the same as if the transactions had been executed in some serial order.

3. View Serializability: This is an even more relaxed form of serializability. It allows for more interleaving of operations from different transactions than conceptual serializability, as long as the final result is the same as if the transactions had been executed in some serial order, and as long as certain constraints on the operations are met. These constraints typically involve the values read and written by the operations.
