Assume that a student table in a university database had an index on StudentID (the primary key) and indexes on Major, Age, MaritalStatus, and HomeZipCode (all second- ary keys). Further, assume that the university wanted a list of students majoring in MIS or computer science, over age 25, and married OR students majoring in computer engi- neering, single, and from the 45462 zip code. How could indexes be used so that only records that satisfy this quali- fication are accessed? 3
