CIS355A Week 6 Lab—Database Connectivity

 

OBJECTIVES

• Programmatic access to a MySQL database to add and display records

 

 

PROBLEM:  Student Management System

A teacher needs the ability to store and retrieve student data. This includes

• student name;
• three test scores;
• average; and
• letter grade.

 

FUNCTIONAL REQUIREMENTS

You can code the GUI by hand or use NetBeans GUI builder interface.

Create a GUI which allows for input and display of student data.

It should include buttons to save a record, display all records.

 

Create a database and table to store student name and three test scores. (Note that average and grade are calculated by app.)

 

Student class

Create a Student class to manage the student data. It should have private instance variables of

• student name; and
• three test scores.

The class must have the following methods.

• A default and parameterized constructor
• Sets/gets for all instance variables
• A get method to calculate and return the average
• A get method to calculate and return the letter grade
• toString to display the name of the student

 

StudentDB class

Create a StudentDB class that is used to create a connection and interface with the database.

 

This class should have two methods.

• getAll—reads data from database, returns data in an arraylist of student objects
• add—writes a record to the database

 

GUI class

 

Insert button will take the info from the GUI (student name and three test scores) and insert a record into the table.  Input should be cleared from the textboxes.

 

Display button will read the data from the database and creates a report in Console window, sample format below.

 

Name                    Test1     Test2     Test3        Avg        Grade

Bruce Wayne          90         95         98            94.3       A

Clark Kent              65         70         90            75.0       C

CODE STYLE REQUIREMENTS

• Include meaningful comments throughout your code.
• Use meaningful names for variables.
• Code must be properly indented.
• Include a comment header at beginning of each file, example below.

/****************************************************

Programmer's Name: Student Name 
Program Description: Describe here what this program will do 
***********************************************************/

DELIVERABLES

Submit as a SINGLE zip folder

• all java files; and
• the Lab report.

 

Follow assignment specification regarding class/method names.

Note that your Java file name must match class name (DO NOT rename).

Lab Week ____

 

Objective/Purpose of the program

Briefly describe the program’s requirements.

 

 

Analysis/Design 

Describe the approach/structure of program. What classes/functions were used?

 

 

Testing/Results

Does your program satisfy all requirements of the lab?

If yes, how did you test it? Indicate test cases used, expected values, and show results with screen shots.  For example:

 

Case	Description	Test Data	Expected Result	Actual Result
1	Describe what you are testing	Specify the test data	What is expected	Actual results – reference an image that you include below.

 

If any requirements are NOT met, document the known issues.  What did you do to try to solve them?

Make sure you demonstrate in your testing the parts that are working correctly.

 

Conclusions / Lessons Learned

What difficult problems did you encounter, and how did you handle them?

What new concepts did you learn/reinforce with this lab?

Is there anything you would have done differently?
