Technical Implementation

Backend Development with Laravel

Laravel, a powerful PHP framework, serves as the backbone of the Project Management System, providing a structured and efficient environment for building scalable web applications.

• Routing and Controllers: Manages HTTP requests and directs them to appropriate controllers for processing.
• Eloquent ORM: Facilitates seamless interaction with the MySQL database through an intuitive ActiveRecord implementation.
• Middleware: Handles authentication, authorization, and other request filtering mechanisms.
• Blade Templating Engine: Renders dynamic views, ensuring a cohesive and interactive user interface.

// Example: ProjectController.php
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Project;
use App\Models\Review;
use Illuminate\Support\Facades\Auth;

class ProjectController extends Controller
{
    // Display a listing of projects
    public function index()
    {
        $projects = Project::with('reviews')->where('user_id', Auth::id())->get();
        return view('projects.index', compact('projects'));
    }

    // Store a newly created project
    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required|string|max:255',
            'description' => 'required|string',
            'file' => 'required|mimes:pdf,doc,docx|max:2048',
        ]);

        $project = new Project();
        $project->user_id = Auth::id();
        $project->title = $request->title;
        $project->description = $request->description;
        if($request->hasFile('file')){
            $project->file_path = $request->file('file')->store('projects');
        }
        $project->save();

        return redirect()->route('projects.index')->with('success', 'Project submitted successfully.');
    }

    // Show the form for editing the specified project
    public function edit($id)
    {
        $project = Project::findOrFail($id);
        // Authorization check can be added here
        return view('projects.edit', compact('project'));
    }

    // Update the specified project in storage
    public function update(Request $request, $id)
    {
        $project = Project::findOrFail($id);
        // Authorization check can be added here

        $request->validate([
            'title' => 'required|string|max:255',
            'description' => 'required|string',
            'file' => 'nullable|mimes:pdf,doc,docx|max:2048',
        ]);

        $project->title = $request->title;
        $project->description = $request->description;
        if($request->hasFile('file')){
            $project->file_path = $request->file('file')->store('projects');
        }
        $project->save();

        return redirect()->route('projects.index')->with('success', 'Project updated successfully.');
    }
}

Advanced Database Design with MySQL

A cornerstone of the Project Management System is its comprehensive database architecture, meticulously designed to handle intricate data relationships and ensure optimal performance. The database comprises over 30 tables, each serving a distinct purpose within the system. Key tables include:

• Users: Stores user information, roles, and authentication credentials.
• Projects: Contains project details submitted by students.
• Reviews: Holds faculty evaluations and feedback for each project.
• Notifications: Manages real-time notifications sent to users.
• Roles and Permissions: Defines access control mechanisms.
• Audit Logs: Tracks changes and activities within the system for accountability.

Sample Database Schema

-- Users Table
CREATE TABLE users (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    email VARCHAR(255) UNIQUE NOT NULL,
    password VARCHAR(255) NOT NULL,
    role_id BIGINT UNSIGNED,
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    FOREIGN KEY (role_id) REFERENCES roles(id)
);

-- Roles Table
CREATE TABLE roles (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) UNIQUE NOT NULL,
    description TEXT,
    created_at TIMESTAMP,
    updated_at TIMESTAMP
);

-- Projects Table
CREATE TABLE projects (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    user_id BIGINT UNSIGNED NOT NULL,
    title VARCHAR(255) NOT NULL,
    description TEXT NOT NULL,
    file_path VARCHAR(255),
    status ENUM('Submitted', 'Under Review', 'Reviewed') DEFAULT 'Submitted',
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id)
);

-- Reviews Table
CREATE TABLE reviews (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    project_id BIGINT UNSIGNED NOT NULL,
    faculty_id BIGINT UNSIGNED NOT NULL,
    score INT CHECK (score >= 0 AND score <= 100),
    feedback TEXT,
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    FOREIGN KEY (project_id) REFERENCES projects(id),
    FOREIGN KEY (faculty_id) REFERENCES users(id)
);

-- Notifications Table
CREATE TABLE notifications (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    user_id BIGINT UNSIGNED NOT NULL,
    message TEXT NOT NULL,
    read BOOLEAN DEFAULT FALSE,
    created_at TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id)
);

Middleware and Security

Ensuring the security and integrity of data is paramount. The system employs Laravel's middleware to handle authentication and authorization, safeguarding sensitive operations and data access. Additionally, encryption techniques are implemented to protect user credentials and project files.

// Example: Authenticate Middleware
<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class Authenticate
{
    public function handle($request, Closure $next, ...$guards)
    {
        if (!Auth::check()) {
            return redirect()->route('login')->with('error', 'Please log in to access this page.');
        }

        return $next($request);
    }
}

Automated Notifications

The system utilizes Laravel's notification channels to send real-time alerts to users regarding project submissions, updates, and feedback. This ensures timely communication and enhances user engagement.

// Example: ProjectSubmitted Notification
<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;

class ProjectSubmitted extends Notification
{
    use Queueable;

    private $project;

    public function __construct($project)
    {
        $this->project = $project;
    }

    public function via($notifiable)
    {
        return ['database', 'mail'];
    }

    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->line('Your project has been successfully submitted.')
                    ->action('View Project', url('/projects/'.$this->project->id))
                    ->line('Thank you for using our application!');
    }

    public function toArray($notifiable)
    {
        return [
            'project_id' => $this->project->id,
            'message' => 'Your project "' . $this->project->title . '" has been submitted successfully.',
        ];
    }
}
