CIS355A Week 6 Lab - Database Connectivity Student Management System

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.

PRG 421 Week 4 Individual Analyze Assignment Analyzing a Multithreaded Program

Deadlock occurs when no processing can occur because two processes that are waiting for each other to finish. For example, imagine that two processes need access to a file or database table row in order to complete, but both processes are attempting to access that resource at the same time. Neither process can complete without the other releasing access to the required resource, so the result is deadlock.
Read and analyze code in the linked document that spawns two different threads at the same time.
In a Microsoft® Word file, predict the results of executing the program, and identify whether a deadlock or starvation event will occur and, if so, at what point in the code.
Submit your Word file to the Assignment Files tab.
1. Predict the results of executing the program.
2. Identify whether a deadlock or starvation event will occur and, if so, at what point in the code.

CIS355A Week 6 Practice Program - Pizza Data/IO

Introduction - Connecting and Manipulating Databases
This week you’re going to replace the File IO operations your completed last week and replace them with database operations. During this exercise you will see the advantage of making the effort in creating a 3-tiered architecture that encapsulations the operations into the appropriate layer.
Use your OmnyBus MySQL Account
Updating the Pizza Order Program:
Here is what you will need to do to get the Pizza Program to work.
In the OmnyBus EDUPE server management application:
Open the database you created.
Create a table called "PizzaOrder" with the following fields
1) id as an Int, set to primary key, set Autoincrement = yes
2) firstName as a varchar of length 50
3) lastName as a varchar of length 50
4) size of type small int
5) cheese as a tinyint (MySQL boolean)
6) sausage as tinyint
7) ham as a tinyint
8) total as a double
In the Netbeans (or Eclipse) project ensure that the MYSQL jar file is correctly referenced (in your assignments, you will have to move this file into your project and set the path to the jar file):
Right click on the project name, then select "Properities".
Select libaries
Confirm that the mysql-connector.jar file is listed in the "Compile Time Libaries:"
See the following that demonstrates how to set the driver, jar reference path:

In the Data project, DataIO class update the following constant fields to showy our credential information:
CONNECTION_STRING
USER_NAME
PASSWORD
In the DataIO class there are TODO items (select WINDOW|ACTION ITEM to see list of todo, click to take you to the code location). You are then asked to modify the following methods to interact with the database.
add method
delete method
update method
getList method

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.
Field Type
CustomerName varchar(30)
CustomerAddress varchar(50)
FlooringType varchar(10)
FloorArea Double
FloorCost Double
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.

Analysis and Design (Due Week 4)
In Week 4, you will complete the analysis and design for the project. You will use the guidelines described above and the grading rubric below to complete this document. You will create the following items.
1. Request for new application
2. Problem analysis
3. List and description of the requirements
4. Interface storyboard or drawing
5. Design flowchart or pseudocode

Contact list application with JavaDB

Problem/Scenario: Computers and Personal Digital Assistant (PDA) devices help to organize many aspects of a user’s life. A common application of these devices is a contact list where items such as name and phone number can be stored. You will create a similar application. The company you work for is a very small business and their record keeping is quite outdated. All of the contacts that the company uses are kept on paper. As a newly hired JAVA developer your first task is to create a company contact list application to help control contact information.

1. Create a Design Document showing a mockup of what the new application will look like and include any details about how it will function. Assume you will present this document to the management of your company.
2. Create a JAVA application to create and maintain a contact list. The contact list should include the contact name, address, city, state, zip and phone number. In addition, the contact list application must have the ability to Add, Delete, Update and Find contacts as needed.
3. The contact list application will display appropriate messages when a user successfully adds, updates or deletes a contact and will also display any error messages when a given user action fails.
4. You must create a database of your choice to store the contact information.

Note: This tutorial only include tasks 2-4.
