CIS355A Week 4 Course Project Student Assignment Grading Analysis and Design

You are a software development in a software development company called “Academic Support Technologies” (AST) and your company is attempting to complete the prototype of a grading application that they purchased from another development firm. However, the original developer did not complete the entire application and just have a working program shell, where not all the operation and graphical user interfaces are complete. In addition, there is no analysis and design information provided—only the program shell.

Your Software Engineering Manager has tasked you to review the program and document the structure of the program by creating the Class/Object diagram of the existing application. Then once you have completed documenting the program structure, you are to complete the missing programming operations and graphical user interfaces.

All the project files and supporting project have been provided.
Description: Student Assignment Grading

The Student Grading application will keep track of one student’s assignment grade information for any number courses, and each course can be anywhere from 1 to 16 weeks long. For each week of the course, the assignments are (1) threaded discussion score, (2) quiz score, (3) lab assignment score, and an exam. Not all the week’s will have each of the assignment score recorded, and the final week of the course will have a final exam score only.

A student will be able to keep assignment scores for any number of courses, and each course will have the school name, the course number, the course title, and how many weeks there are in the course.
For a selected course, the application will allow the user to enter the scores, and once the scores are entered for the week the application will calculate the weekly total and the weekly average, along with the course running total score, running average, and letter grade to date (based on course syllabus grade breakdown).

The database will contain two tables (1) Courses and (2) Assignments, using the following table names and fields

1. Course
   1. Id
   2. School
   3. Number
   4. Title
2. Assignments
   1. Id
   2. CourseID
   3. WeekNumber
   4. TDA
   5. Lab
   6. Quiz
   7. Test

The application will display a table that displays the following for each course that is recorded:

1. Course Number
2. Course Title
3. Course Grade

While the application and database will be user name and password protected, it is outside the scope of this project to provide a complete, robust, and secure authentication component. So, for the purposes of this development, you will just store the user name and password comma separated value text file.

Design Requirements
The program design shall adhere to the following design requirements:

1. The program will be constructed using a 3-tier architecture (1) data, (2) business, and (3) presentation tier and each tier will only implement the operations appropriate for the tier.
2. The graphical user interface will be constructed using a tab panel interface, with each tab containing only those operations related to the tab heading.
3. The order of the tabs will be in logical sequence.
4. The graphical user interface will contain a main menu bar, and there shall be a menu for each tab that mirrors the operations on the tab.
5. Each menu item will have a logical name and short cut key assigned.
6. Each “active” control (i.e. radio button, command button…) shall have a tooltip describing the operation the control provides.
7. There shall be a logical, sequential tab order for the input controls on the form.
8. All class members, both variables and methods, shall by default be made private.
9. Access to any class/object data member shall only be done through getters and setters.
10. Methods shall only be made public if it is necessary for other objects to call the methods.
11. Private variables shall only be access through getters and setters.
12. All setters will have validation logic to ensure the private variable is always in a stable state.

FUNCTIONAL REQUIREMENTS
The program operations will adhere to the following requirements:

1. The maximum points of all the assignments is 1000 points.
2. Each input score item shall be validated against a lower and upper bound.
3. The lower and upper bounds of each of the assignments shall be stored in the database or a file.
4. The user must authenticate into the program when it starts.
5. The user name and password shall be stored in a file (which simulates an authentication component).
6. The running total, running average, and current grade shall only include scores that have been recorded.
7. The threaded discussion score shall be calculated by the user being able to select whether a student attended, or posted a note on a day of the week, for each of the 7 weeks.
8. If a student attends at least three days, the student will receive full credit for the weekly threaded discussion score.
9. The automatically assigned threaded discussion score, can be overridden to a lower, or higher score, but within the limits of the minimum and maximum scores.
10. The weekly total, weekly average, running total, and running average shall be updated any time one of the dependent fields is updated.
11. Database operations shall be secure and be written to minimize SQL injection or other transport type attacks.

Analysis and Design
In Week 4 you will create an analysis and design document that consists of:

1. Document the current “as is” structure of the program.
2. Create a class/Object Diagram (this can be done in any drawing tool, or even hand drawn and take a picture).

Implementation
The final program shall:

1. Go through the TODO action items in the course shell project starting in the business layer, then go to the data layer, and then the presentation.
2. If you correctly make all the TODO changes the program will work as expected.
3. Contain all files, and referenced projects/jar files

CIS355A Week 6 Lab Database Stocks4U Portfolio Management System

OBJECTIVES

Add persistent data storage to your Week 5 Lab using the MySQL Database.

PROBLEM: Stocks4U Portfolio Management System
The portfolio management system you developed for Stocks4U needs the ability to save and restore a user’s data from a MySql Database.

FUNCTIONAL REQUIREMENTS

• The functional requirements of the Stocks4U application have not changed, and the Graphical User Interface has not changed from Week 5.

StockIO class

Modify the StockIO class to read and write the stock information to and from a MySQL database. Called “StocksDB”

This class should have two methods.

• getData—reads data from file, returns data in array list of stock objects

CIS355A Final Exam Essay Questions

1. (TCOs 1–6) TicketsRUs needs an application to calculate ticket prices. There are three ticket prices:

• Orchestra $85 each
• Mezzanine $70 each
• Balcony $45 each

There is also a 15% discount on matinee performances.

Your application has the GUI shown below.

With the following named components:
[table]
Component, Type, Purpose
txtNum, JTextField, Input for number of tickets
chkMatinee, JCheckBox, Check if matinee performance
radOrchestra, JRadioButton, Check for orchestra tickets
radMezzanine, JRadioButton, Check for mezzanine tickets
radBalcony, JRadioButton, Check for balcony tickets
btnCalc ,JButton, Click to calculate price
txtEach, JTextField, Displays price of each ticket
txtTotal, JTextField ,Displays total price
[/table]
Clicking the CalcPrice button should determine the price per ticket and the total price based on the user’s input and display in txtEach and txtTotal. You should make sure the number of tickets is entered and a ticket type is selected, otherwise give an error message.

The action listener for btnCalc is set up as follows.

1 2 3 4 5

btnCalc.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { calcPrice();  //write the code for this method } });

Write the calcPrice method that is called by the action listener. This class method has access to all of the GUI components. You DO NOT HAVE TO CODE THE GUI. ONLY write the code for this method which does all the work. The header for the method is:

1	private void calcPrice() (Points : 20)

2. (TCOs 1–6) Employees at a certain company get a yearly bonus based on years of service. The bonus is a percentage of their annual salary based on the table below.

5 – 14	7%
15++	12%

Create a class called Employee that can be used for this.
It should have attributes of

• Name;
• Years; and
• Salary.

Create the following methods.

• Default constructor to initialize all attributes
• Get/Set for name, years, salary
• Get to calculate and return bonus rate
• Get to calculate and return bonus amount

This class will be used with the Bonus Calculator GUI shown below.

With the following named components:

[/table]
You DO NOT have to code the GUI.
The action listener for btnCalc is set up as follows.

1 2 3 4 5

btnCalc.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { calcBonus();  //write the code for this method } }); (Points : 20)

3. (TCOs 1–6) A trucking company has an application to track data from their trucks regarding miles driven and fuel used each month. This information is stored in a file named “trucks.txt” . This table has the following fields.
[table]
TruckID, Truck Number (String)
Miles , Miles Driven (double)
Fuel , Fuel Used (double)
[/table]
Format of file – note the # delimiter character between fields
TruckID#miles#fuel

The application has a button that is clicked to read each line of the file and calculates and displays in the console the total miles driven, total fuel used, and average miles per gallon. You DO NOT have to write a separate class to process the data. The output in the console should look like:
Total miles driven by all trucks xxx
Total gallons of fuel used yyy
Average miles per gallon for the fleet zz.zz

The class method readFile() is called by the action listener to do the work. Write the code for this method. (Points : 15)

4. (TCOs 1–6) Assume a College database has a table to keep transcript data on students. The transcript table has fields for SSN, TotalPoints, and TotalCredits. You are to design an application that allows a student to input their SSN into a textbox (txtSSN) and press a button (btnCalc). The students GPA is calculated (divide points by credits) and displayed in txtGPA.

Describe the process/steps to do this. Write pseudocode/comments or code where you can. You DO NOT have to have complete working code, you need to describe the necessary steps and WHERE things need to be coded. (Points : 15)

Your application must include at least three tabs. The user will choose wood flooring or carpet, enter the length and width of the floor, as well as the customer name and address. The application will compute the area of the floor and the cost of the flooring considering that wood floor is $20 per square foot and carpet is $10 per square foot. A summary should be displayed, either in a tab or another window, listing the customer name and address, floor selection, area, and cost. This information should also be stored in the MySQL database table. The program should validate that all information is entered and that the length and width are numeric values. Any numeric or currency values must be formatted appropriately when output. Recommendations for the components used for input are

• radio buttons—flooring type (wood or carpet).
• text fields—customer name, customer address, floor length, and floor width
• buttons—calculate area, calculate cost, submit order, display order summary, display order list.

The MySQL database table is called flooring and has the following description:

Field	Type
CustomerName	varchar(30)
CustomerAddress	varchar(50)
FlooringType	varchar(10)

CIS355A Week 4 Course Project Flooring Application Analysis and Design

Developing a graphical user interface in programming is paramount to being successful in the business industry. This project incorporates GUI techniques with other tools that you have learned about in this class.
Here is your assignment: You work for a flooring company. They have asked you to be a part of their team because they need a computer programmer, analyst, and designer to aid them in tracking customer orders. Your skills will be needed in creating a GUI program that calculates the flooring cost and stores the order in the database.
The project has three components: an analysis and design document, the project code, and a user manual. The analysis and design document is due Week 4. The code and user manual are due in Week 7. It is suggested that you begin working on the code in Week 5, which should give you ample time to complete the project. You will find that the lectures and lab assignments will prepare you for the Course Project.

Guidelines
Your application must include at least three tabs. The user will choose wood flooring or carpet, enter the length and width of the floor, as well as the customer name and address. The application will compute the area of the floor and the cost of the flooring considering that wood floor is $20 per square foot and carpet is $10 per square foot. A summary should be displayed, either in a tab or another window, listing the customer name and address, floor selection, area, and cost. This information should also be stored in the MySQL database table. The program should validate that all information is entered and that the length and width are numeric values. Any numeric or currency values must be formatted appropriately when output. Recommendations for the components used for input are

• radio buttons—flooring type (wood or carpet);
• text fields—customer name, customer address, floor length, and floor width; and
• buttons—calculate area, calculate cost, submit order, display order summary, display order list.

The MySQL database table is called flooring and has the following description:
[table]
Field, Type
CustomerName, varchar(30)
CustomerAddress, varchar(50)
FlooringType, varchar(10)
FloorArea, Double
FloorCost, Double
[/table]
In addition to entering new customer orders, your application should list all customer orders stored in the database. These will be viewed as a list, in a text area, and will not be updated by the user.

CIS355A Week 2 Lab Developing a GUI Application

OBJECTIVES

• Create a GUI that usesJTextField, JLabel, and JButton.
• Write event handlers to process user data.

PROBLEM: Health Profile App
GymsRUs would like to replace their console program with an updated app using a graphical user interface. You will use the HealthProfile class that you created in the Week 1 Lab and build a GUI for it.

FUNCTIONAL REQUIREMENTS
Make sure your HealthProfile class from the Week 1 Lab is in a named package, not default (i.e., package lab1).

You must ADD the project that contains the HealthProfile class to this week’s project by
right click project, go to properties; and
click Libraries, Add Project, click OK.

Then you will be able to reference your existing class as
import lab1.HealthProfile.

Your project will have three classes:

• HealthProfile class from Week 1 Lab
• HealthProfileGUI class
• Lab2Main class

Your HealthProfildGUI class should have the following components (see sample GUI below):

• JTextField objects to enter: name, age, height in feet, height in inches, weight in pounds
• JButton objects to display results, clear the GUI
• JTextField objects to display the BMI, category, and max heart rate
• JLabels to describe all textboxes

You are free to layout and design your GUI as you like as long as it includes these components.

Add default and parameterized constructors to your HealthProfile class. The parameterized constructor should have five arguments: the name, age, weight, height in feet, and height in inches. Note it should convert the height to inches to store in the private instance variable.
Code event handlers for each button:

• Display: Make sure all user input is present and valid
  Use the HealthProfile class to process the data
  Display the results on the GUI
• Clear Clear all text boxes on the GUI

Sample GUI

CIS355A Week 1 Lab Developing an OOP Console Application

OBJECTIVES

• Create a class in java with appropriate methods.
• Process user input with the class using the scanner for keyboard input and console output.

PROBLEM: Health Profile Console Program
GymsRUs has a need to provide fitness/health information to their clients, including BMI and maximum heart rate. Your task is to write a console program to do this.

Body mass index (BMI) is a measure of body fat based on a person’s height and weight. BMI can be used to indicate if you are overweight, obese, underweight, or normal.The formula to calculate BMI is

The following BMI categories are based on this calculation.
[table]
Category, BMI Range
Underweight, less than 18.5
Normal, between 18.5 and 24.9
Overweight, between 25 and 29.9
Obese, 30 or more
[/table]
Max heart rate is calculated as 200 minus a person’s age.

FUNCTIONAL REQUIREMENTS
Design and code a class called HealthProfile to store information about clients and their fitness data. The attributes (name, age, weight, and height) are private instance variables. The class must include the following methods.

method,	description
setName,	Receives a value to assign to private instance variable
setAge,	Receives a value to assign to private instance variable
setWeight,	Receives a value to assign to private instance variable
setHeight,	Receives TWO inputs (height in feet\, inches). Converts and stores the total INCHES in private instance variable
getName,	Returns private instance variable
getAge,	Returns private instance variable
getWeight,	Returns private instance variable
getHeight,	Returns private instance variable (inches)
getBMI,	Calculates and returns BMI
getCategory,	Returns category based on BMI
getMaxHR,	Calculates and returns maximum heart rate

Create a SEPARATE TEST CLASS, Lab1Main, to prompt for user input and display output using the HealthProfile class. Process multiple inputs using a loop.You can assume all user input is valid.

SAMPLE OUTPUT

Enter name or X to quit: John Smith
Your age: 35
Your weight: 200
Your height – feet: 6
Your height – inches: 0

Health Profile for John Smith
BMI: 27.1
BMI Category: overweight
Max heart rate: 185

Enter name or X to quit: Ann Jones
Your age: 50
Your weight: 120
Your height – feet: 5
Your height – inches: 2
