3.17. Composite and multivalued attributes can be nested to any number of lev els. Suppose we want to design an attribute for a STUDENT entity type to keep track of previous college education. Such an attribute will have one entry for each college previously attended, and each such entry will be com posed of college name, start and end dates, degree entries (degrees awarded at that college, if any), and transcript entries (courses completed at that col lege, if any). Each degree entry contains the degree name and the month and year the degree was awarded, and each transcript entry contains a course name, semester, year, and grade.
