Isolation is a sufficient but not necessary condition to achieve correctness. Consider an application that reserves seats for a concert. Each reservation transaction (1) reads the list of seats that have not yet been reserved, (2) presents them to a potential customer who selects one of them, and (3) marks the selected seat as reserved. An integrity constraint asserts that the same seat cannot be reserved by two different customers. Describe a situation in which two such transactions that reserve two different seats execute in a nonisolated fashion but are nevertheless correct.
