A student database may include indexes on fields such as major, age, marital status, and home zip code in addition to the main key, which is the student's unique identifier (all secondary keys). Let's assume the school wants a list of MIS or CS majors over the age of 25 who are married and from the 45462 zip code OR a list of CS majors under the age of 25 who are single and from the 45462 the code. Is there a way to utilize indexes to restrict access to just the records that meet this criterion?
