IT 145 Final Project Solution
Overview
A successful career in software development depends on a thorough understanding of the fundamentals of object-oriented programming and best practices for software development. Your final project for this course will require you to apply the knowledge you have obtained prior to and during this course to the development of a simple, working program and accompanying process documentation. Professionals in software development document their process including requirements, design decisions, and defects for several different reasons as follows:
To track what has been accomplished
To track when items were completed in order to maintain a schedule
To justify why a product works the way it does (verification and validation)
To provide resources if a new team member is added so he or she can catch up
To see where the most defects are being injected in order to prevent them
To review what happened during the project in order to create new ways of improving the process
For your development project, you will imagine you are in charge of managing a zoo’s computer infrastructure. There are many aspects of a zoo that need to be
in place to keep it running. Two of those aspects are controlling data access and monitoring animal activities in exhibits. You will select which of these key
components you wish to develop. Both options require at least two classes and for the design to be broken into multiple methods. Select one of the options
provided in the prompt below and create your program and process documentation based on the specified requirements.
The final project for this course is the creation of an authentication or monitoring system. The final project represents an authentic demonstration of
competency because it involves application of real-world Java programming. The project is divided into one milestone and several final project journal
assignments, which will be submitted at various points throughout the course to scaffold learning and ensure quality final submissions. Milestone One will be
submitted in Module Five. The final project will be submitted in Module Seven.
In this assignment, you will demonstrate your mastery of the following course outcomes:
Implement appropriate variables, operators, methods, and classes as they are used in object-oriented programming for developing successful programs
Utilize appropriate syntax and conventions in terms of their best practice and use in programming
Debug coding errors by testing existing code, identifying errors, and correcting errors for improved functionality
Assemble basic, working programs that effectively integrate essential elements of object-oriented programming
Prompt
You have assumed the role of managing the technology infrastructure at a zoo. You will develop a working program (either an authentication system or a
monitoring system) for the zoo designed to follow the specifications outlined in the overview. You will also provide detailed documentation describing your
development process. Select from one of the following options as the basis of your program.
Option 1: Authentication System
For security-minded professionals, it is important that only the appropriate people gain access to data in a computer system. This is called authentication. Once
users gain entry, it is also important that they only see data related to their role in a computer system. This is called authorization. For the zoo, you will develop
an authentication system that manages both authentication and authorization. You have been given a credentials file that contains credential information for
authorized users. You have also been given three files, one for each role: zookeeper, veterinarian, and admin. Each role file describes the data the particular role
should be authorized to access. Create an authentication system that does all of the following:
Asks the user for a username
Asks the user for a password
Converts the password using a message digest five (MD5) hash
o It is not required that you write the MD5 from scratch. Use the code located in this document and follow the comments in it to perform this
operation.
Checks the credentials against the valid credentials provided in the credentials file
o Use the hashed passwords in the second column; the third column contains the actual passwords for testing and the fourth row contains the
role of each user.
Limits failed attempts to three before notifying the user and exiting the program
Gives authenticated users access to the correct role file after successful authentication
o The system information stored in the role file should be displayed. For example, if a zookeeper’s credentials is successfully authenticated, then
the contents from the zookeeper file will be displayed. If an admin’s credentials is successfully authenticated, then the contents from the admin
file will be displayed.
Allows a user to log out
Stays on the credential screen until either a successful attempt has been made, three unsuccessful attempts have been made, or a user chooses to exit
You are allowed to add extra roles if you would like to see another type of user added to the system, but you may not remove any of the existing roles.
Option 2: Monitoring System
As a zookeeper, it is important to know the activities of the animals in your care and to monitor their living habitats. Create a monitoring system that does all of
the following:
Asks a user if they want to monitor an animal, monitor a habitat, or exit
Displays a list of animal/habitat options (based on the previous selection) as read from either the animals or habitats file
o Asks the user to enter one of the options
Displays the monitoring information by finding the appropriate section in the file
Separates sections by the category and selection (such as “Animal - Lion” or “Habitat - Penguin”)
Uses a dialog box to alert the zookeeper if the monitor detects something out of the normal range (These will be denoted in the files by a new line
starting with *****. Do not display the asterisks in the dialog.)
Allows a user to return to the original options
You are allowed to add extra animals, habitats, or alerts, but you may not remove the existing ones.
Specifically, the following critical elements must be addressed:
I. Process Documentation: Create process documentation to accompany your program that addresses all of the following elements:
A. Problem Statement/Scenario: Identify the program you plan to develop and analyze the scenario to determine necessary consideration for
building your program.
B. Overall Process: Provide a short narrative that shows your progression from problem statement to breakdown to implementation strategies. In
other words, describe the process you took to work from problem statement (your starting point) to the final product. Your process description
should align to your end resulting program and include sufficient detail to show the step-by-step progress from your problem statement
analysis.
C. Pseudocode: Break down the problem statement into programming terms through creation of pseudocode. The pseudocode should
demonstrate your breakdown of the program from the problem statement into programming terms. Explain whether the pseudocode differs
from the submitted program and document any differences and the reason for changes.
D. Methods and Classes: Your pseudocode reflects distinct methods and classes that will be called within the final program. If the pseudocode
differs from the submitted program, document the differences and reason for changes.
E. Error Documentation: Accurately document major errors that you encountered while developing your program.
F. Solution Documentation: Document how you solved the errors and what you learned from them.
II. Program: Your working program should include all of the specified requirements. The comments within your program will count toward the assessment of the documentation aspects of your submission.
A. Functionality
1. Input/Output: Your program reads input from the user and uses system output.
2. Control Structures: Your program utilizes appropriate control structures for program logic.
3. Libraries: Your program utilizes standard libraries to pull in predefined functionality.
4. Classes Breakdown: Your program is broken down into at least two appropriate classes.
5. Methods: Your program utilizes all included methods correctly within the classes.
6. Error Free: Your program has been debugged to minimize errors in the final product. (Your program will be run to determine
functionality.)
B. Best Practices: These best practices should be evident within your working program and process documentation.
1. Formatting Best Practices: Provide program code that is easy to read and follows formatting best practices as defined by the industry,
such as with indentation.
2. Documentation Best Practices: Include comments where needed within the program in appropriate detail for communicating purpose,
function, and necessary information to other information technology (IT) professionals.
3. Coding Best Practices: Ensure your program supports clean code through descriptive variable names.
