CEN206 — Term Project Guideline & Evaluation Manual

Overview

You will develop the same application in three languages — Java, C/C++, and C# — across two phases: a console application (Midterm) and a desktop GUI extension (Final). Each team maintains three private repositories (one per language) forked from the provided templates. Submission dates and instructor information are provided in the term-specific document on Microsoft Teams.

Project Constraints (MÜDEK Ölçüt 5.5 — PÇ.3)

Your application must address at least ONE realistic constraint: budget limits, time pressure, user accessibility, data security, regulatory compliance, or privacy. Document the chosen constraint and reference an engineering standard where applicable (e.g. IEEE 730, ISO/IEC 25010).


2. Assessment Structure

The project grade is composed of the following components. MÜDEK v3.0 Ölçüt 3.2 requires Skill-category outcomes to be evidenced by practical project outputs, not solely by written exams.

Component Description Weight LOs Measured
A1 Midterm Project — Console App + All Design Documents 60% LO.1, LO.2, LO.3
A2 Quiz — Theory + Application 40% LO.1–LO.5
MID-SEMESTER 40% · END-OF-SEMESTER 60%
F1 Final Project — GUI Extension + Updated Design Documents 70% LO.1–LO.7
F2 Final Quiz — Comprehensive 30% LO.1–LO.7
MÜDEK v3.0 Evidence Notes
  • Skill outcomes (LO.2–LO.7): project output is the primary evidence — quiz grade alone is insufficient.
  • A1 and F1 project submissions serve as the primary Skill evidence.
  • Design documents (PlantUML, UMPLE, Figma, draw.io, ProjectLibre) are required at Midterm and must be updated at Final.
  • The project also develops teamwork (PÇ.6), written/oral communication (PÇ.8), and project management (PÇ.12) skills.

3. Learning Outcomes (LO — MÜDEK v3.0)

LO Learning Outcome Bloom Category A1 A2 F1 F2
LO.1 Explains OOP fundamentals (encapsulation, inheritance, polymorphism, abstraction) Understand Knowledge
LO.2 Designs and implements classes, objects, methods (constructors, access modifiers, static) Apply Skill
LO.3 Applies inheritance and polymorphism (abstract classes, interfaces, overriding) Apply Skill
LO.4 Uses exception-handling mechanisms (try-catch) to manage runtime errors Apply Skill
LO.5 Creates type-independent, reusable components using Generics Analyze Skill
LO.6 Implements pluggable storage (Binary + SQLite + MySQL) via Repository + Strategy pattern Apply Skill
LO.7 Develops maintainable software using SOLID, design patterns (min. 3), refactoring Synthesize Skill

4. Required Tools

All tools below are mandatory from Midterm — do not defer design tools to Final.

Tool Purpose Output
PlantUML ALL UML diagrams + C4 + Gantt + ER .puml source + PNG
C4 Model Architecture: Context → Container → Component C4-PlantUML .puml + PNG
UMPLE Domain class model / state machines .ump file
Figma Screen wireframes (Console + GUI) PNG / PDF
draw.io Deployment diagram .drawio + PNG
ProjectLibre Gantt chart / WBS .xml file
Maven / CMake / dotnet Build + test + coverage JaCoCo / gcov / coverlet
Doxygen Source documentation PDF only
GitHub Actions CI/CD pipeline .yml workflow

Design-First Workflow

  1. PlantUML class diagram before writing any class code
  2. C4 Model (Context → Container → Component) at Midterm
  3. Figma wireframes: two sets — Console screens (Midterm) + GUI screens (Final)
  4. draw.io Deployment view: modules, runtime, file system, external deps
  5. UMPLE model: domain structure; update when adding Final classes
  6. ProjectLibre Gantt: both phases from day one; update actuals

5. Project Selection

Project ideas are listed in the Appendix section below.

How to Select

  1. Browse the Appendix – Application List at the bottom of this page
  2. Choose one application idea
  3. Record your selection in the shared team spreadsheet on Microsoft Teams
  • Three Repositories Per Team: Same project in Java, C/C++, and C# using the provided templates
  • Team Size: Up to 4 members (individual work also permitted)
  • No Changes: Team composition cannot be altered after work begins
  • No Overlap: Senior and junior students may not form teams together
  • No Reuse: Projects from previous terms or other courses may not be reused
  • Approval: Submit project selection and Gantt plan to instructor before coding
  • Constraint: State at least one realistic constraint (see Section 1)

6. Midterm Phase — Console Application

8.4 Microsoft Teams Submission — Single ZIP

Clone your GitHub repository, add video files into the video/ folder, then ZIP the entire project folder. The repository already contains everything (source, design, report, presentation, release artefacts) — you only need to add the videos.

cen206-hw-name-surname.zip
└── cen206-hw-name-surname-java/      # GitHub repo clone (gitignore-filtered)
    ├── src/                           # already in repo
    ├── design/                        # already in repo
    ├── report/                        # already in repo
    ├── presentation/                  # already in repo
    ├── docs/                          # already in repo
    ├── release/                       # GitHub Release tar.gz files downloaded here
    ├── video/                         # ⚠ ADD VIDEOS HERE (not committed to GitHub)
    │   ├── video-name1-surname1.mp4   # one per member, max 4 min
    │   ├── video-name2-surname2.mp4
    │   └── ...
    └── ...                            # all other repo files

ZIP Submission Steps

  1. git clone your repository (or download as ZIP from GitHub)
  2. Download all tar.gz files from your GitHub Release into release/ folder
  3. Place each team member's video (.mp4, max 4 min) into the video/ folder
  4. ZIP the entire project folder → cen206-hw-name-surname.zip
  5. Upload to Microsoft Teams assignment

Repeat for all three repositories (-java, -cpp, -csharp) or combine them in one ZIP.

GitHub Repository URLs in Report (Mandatory)

The first page of your project report MUST include all three GitHub repository URLs:

  • https://github.com/your-username/cen206-hw-name-surname-java
  • https://github.com/your-username/cen206-hw-name-surname-cpp
  • https://github.com/your-username/cen206-hw-name-surname-csharp

Submission Will NOT Be Accepted If

  • GitHub Release is missing or has no tar.gz artefacts
  • GitHub repository URLs not in report
  • Templates not used
  • Repositories not named correctly (-java, -cpp, -csharp)
  • PlantUML .puml source files missing (PNG alone insufficient)
  • C4 Model diagrams missing at Midterm
  • UMPLE .ump not committed
  • Figma console wireframes missing at Midterm
  • draw.io .drawio source not committed
  • ER diagram (.puml) missing
  • Runtime storage switching not implemented (all 3 backends)
  • Doxygen HTML folder submitted instead of PDF
  • Compiled binaries committed to repository
  • Video files committed to GitHub
  • No collaborative commits from all members
  • Coverage below 100%
  • Plagiarism detected

8.5 GitHub Rules

Fork each template and name your repositories:

Language Repository Name Template
Java cen206-hw-name-surname-java eclipse-java-maven-template
C/C++ cen206-hw-name-surname-cpp cpp-cmake-ctest-template
C# cen206-hw-name-surname-csharp vs-net-core-template
  • Private: All three repos must be private
  • Collaborators: Instructor + all team members
  • GitHub Profile: Correct name/surname in Git config; public profile
  • Pre-Commit: Run 1-configure-pre-commit.bat before first commit
  • Releases: midterm-v1.0.0 and final-v2.0.0 mandatory for all repos
  • No Binaries: Never commit .jar, .class, .exe, .o, .dll — configure .gitignore
  • Commit Frequency: Each member commits at least weekly
  • Branching: Feature branches → Pull Requests to main; never commit directly

9. Team Workflow & Engineering Practices

9.1 Git Branching Strategy — GitHub Flow

Branch Type Naming Convention Rule
main main Protected — merge via PR only
feature feature/login-screen One branch per task; delete after merge
bugfix bugfix/null-pointer-fix Branch from main; merge via PR
docs docs/update-readme Documentation-only changes
hotfix hotfix/critical-data-loss Urgent — branch, fix, PR, merge same day

Branch Protection Rules (configure on GitHub)

  • Require PR reviews before merging (min. 1 approval)
  • Require status checks to pass (CI must be green)
  • No force-push, no direct commits to main
  • Repository → Settings → Branches → Add branch protection rule → main

9.2 Commit Message Convention — Conventional Commits

<type>(<scope>): <description>
Type Example
feat feat(storage): implement IRepository<T> + BinaryRepository
fix fix(menu): prevent infinite loop when ESC pressed
test test(student): add unit tests for GPA calculation
docs docs(c4): add container diagram for console layer
refactor refactor(repo): extract StudentRepository to reduce God Class
style style: apply Google Java Format across all source files
ci ci: add JaCoCo coverage report to GitHub Actions
chore chore: update Maven dependencies to latest stable versions

9.3 Pull Request (PR) Process

  1. Create PR from feature branch to main
  2. Title: Conventional Commits format — feat(scope): description
  3. Description: What changed, how to test, screenshots, related Issue #
  4. Assign reviewer — min. 1 team member
  5. CI must pass before merge
  6. Merge strategy: Squash and Merge or Merge Commit
  7. Delete branch after merge

PR Checklist — copy into every PR description

- [ ] Code compiles and all tests pass locally
- [ ] New unit tests added for new functionality
- [ ] Coverage did not decrease
- [ ] Doxygen comments added for all new public methods
- [ ] Design documents updated if architecture changed
- [ ] No binary files committed

11. OOP Requirements

11.0 Storage Architecture — IRepository Pattern

public interface IRepository<T> {
    void save(T entity);
    T findById(int id);
    List<T> findAll();
    void update(T entity);
    void delete(int id);
}
  • Three implementations: BinaryRepository<T>, SqliteRepository<T>, MySqlRepository<T>
  • RepositoryFactory reads config and returns active backend
  • Settings screen: Both console and GUI expose storage switch: [1] Binary [2] SQLite [3] MySQL
  • MySQL requires docker-compose.yml in repo root
  • Each implementation has its own test class

11.1 Class Hierarchy

Design a meaningful hierarchy. Inheritance must be semantically justified — prefer composition over inheritance when not a true "is-a" relationship.

11.2 Encapsulation

  • Access modifiers: private, protected, public applied correctly
  • Getters / Setters: All fields private; expose through accessors

11.3 Polymorphism

  • Method overriding: At least 3 meaningful overrides
  • Runtime polymorphism: Superclass reference → subclass instance
  • Interfaces: At least 2 defined and implemented

11.4 Design Patterns (minimum 3 — one per category)

Category Patterns
Creational Singleton, Factory Method, Abstract Factory, Builder, Prototype
Structural Adapter, Decorator, Facade, Composite, Proxy
Behavioral Observer , Strategy, Command, Template Method, Iterator

For each: state intent, code location, and justification.

11.5 SOLID Principles

Principle Rule
S — Single Responsibility Each class has exactly one reason to change
O — Open/Closed Open for extension, closed for modification
L — Liskov Substitution Subtypes usable wherever supertype expected
I — Interface Segregation Role-specific, focused interfaces
D — Dependency Inversion Depend on abstractions, not concretes
