Consider the schedule of two bank withdrawal transactions shown in Figure 21.13 for which SNAPSHOT isolation leads to an inconsistent database. Suppose that the bank encodes, as an integrity constraint in the database schema, the business rule “The sum of the balances in all accounts owned by the same depositor must be nonnegative.” Then that particular schedule cannot occur.
Although the integrity constraint is nowmaintained, the specification of a particular transaction might assert that when the transaction commits, the database state satisfies a stronger condition. Give an example of a stronger condition that a withdrawal transaction might attempt to impose when it terminates and a schedule of two such transactions at SNAPSHOT isolation that causes them to behave incorrectly.
