HCSD IT314 DBMS Assignment 1: Designing an ERD

Consider the following set of requirements for a University database. Design an ER diagram for this application:

• The university keeps track of each student's name, student number, social security number, current address and phone number, permanent address and phone number, birthdate, sex, class (freshman, graduate), major department, minor department (if any), degree program (B.A., B.S., ... Ph.D.). Some user applications need to refer to the city, state, and zip code of the student's permanent address and to the student's last name. Both social security number and student number are unique for each student. All students will have at least a major department.
• Each department is described by a name, department code, office number, office phone, and college. Both the name and code have unique values for each department.
• Each course has a course name, description, course number, number of credits, level and offering department. The course number is unique for each course.
• Each section has an instructor, semester, year, course, and section number. The section number distinguishes sections of the same course that are taught during the same semester/year; its value is an integer (1, 2, 3, ... up to the number of sections taught during each semester).
• A grade report must be generated for each student that lists the section, letter grade, and numeric grade (0,1,2,3, or 4) for each student and calculates his or her average GPA.

Instructions:

• Printed, Short
• Use Chen's Notation
• To be submitted next Saturday June 25, 2011

IT311 - OOP Laboratory Exercise 5

Java Laboratory Exercise 5

Instructions:

• Due: December 15, 2010 11:59 pm.
• Send the class file and the main program (Household.java and TestHousehold.java)
• Attach and email the files in celticguardiandancingelf@yahoo.com
• Subject: Lastname__it311_labexer5

a.) Create a class named Household that includes data fields for the number of occupants and the annual income, as well as methods named setOccupants(), setIncome(), getOccupants(), and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and the income field to 0. Save this file as Household.java.

b.) Create a program named TestHousehold that demonstrate that each of the methods works correctly.

c.) Create an additional overloaded constructor for the Household class you created. This constructor receives an integer argument and assigns the value to the occupants field. Add any needed statement to TestHousehold to ensure that the overloaded constructor works correctly.

d.) Create a third overloaded constructor for the Household class you created. This constructor receives two arguments, the values of which are assigned to the occupants and income fields, respectively. Alter the TestHousehold program to demonstrate that each version of the constructor works properly.
