A state university stores all student data in a database.

A state university stores all student data in a database. The collected data includes each student’s first name, last name, age, gender, major, nationality, and so forth. The process component of the information system performs all sons of analysis on this data. For example, the university’s DBMS has a built-in query capability that can generate the following information

• How many students are in each major?
• Which major is the fastest growing?
• What is the average age of the student body?
• Among the international students, which country is home to the highest number of students?
• What is the ratio of male to female students in each major?
