Reconsider the situation described for Exercise 2.26 under the assumption that one bank is in the United States and the other is in Canada. As before, the banks use the schema of Figure, except that the Canadian bank uses the social-insurance number assigned by the Canadian government, whereas the U.S. bank uses the social-security number to identify customers. What problems (beyond those identified in Exercise 2.24) might occur in this multinational case? How would you resolve them? Be sure to consider both the scheme and the actual data values in constructing youranswer.
