Let's pretend the Student table in a university database is indexed by StudentID (the primary key), Major, Age, Marital Status, and HomeZipCode (all secondary keys). Assume the school needed a list of students from the 45462 zip code who are either over the age of 25, married, and majoring in MIS or computer science OR who are above the age of 25 and majoring in computer engineering and are single. How can indexes be used to restrict access to records that exactly match these parameters?
