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 secondary 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 engineering, single, and from the 45462 zip code. How could indexes be used so that only records that satisfy this qualification are accessed?
