    Solution

    View serializability  and  conflict serializability are two different concepts used to determine the correctness of a database schedule, ensuring that transactions are executed in a way that preserves consistency. •  Conflict Serializability:  A schedule is conflict serializable if it can be transformed into a serial schedule (where transactions are executed one after another without overlapping) by swapping non-conflicting operations. This is a stricter condition as it requires the preservation of the order of conflicting operations. •  View Serializability:  A schedule is view serializable if it is view-equivalent to a serial schedule, meaning that the initial read, intermediate reads, and final writes are consistent with some serial schedule. View serializability is a broader concept and allows for more schedules to be classified as serializable.
