Database Design Best Practices

Schema Design

// User document example
{
  _id: ObjectId("..."),
  username: "student123",
  email: "[email protected]",
  profile: {
    firstName: "John",
    lastName: "Doe",
    major: "Computer Science",
    year: 2024
  },
  projects: [
    {
      name: "Portfolio Website",
      technologies: ["React", "Node.js", "MongoDB"],
      description: "Personal portfolio built with modern stack"
    }
  ],
  createdAt: new Date(),
  lastLogin: new Date()
}

Indexing Strategy

// Create indexes for better query performance
db.users.createIndex({ "email": 1 }, { unique: true })
db.users.createIndex({ "username": 1 }, { unique: true })
db.projects.createIndex({ "userId": 1, "createdAt": -1 })

Connection Methods

MongoDB Compass (GUI)

• Visual database exploration and query building
• Schema analysis and index optimization
• Real-time performance monitoring
• Document editing with visual interface

Programming Languages

Node.js with Mongoose

const mongoose = require('mongoose');

const connectionString = 'mongodb+srv://username:[email protected]/dbname';

mongoose.connect(connectionString, {
  useNewUrlParser: true,
  useUnifiedTopology: true
});

const userSchema = new mongoose.Schema({
  username: String,
  email: String,
  projects: [{ name: String, tech: [String] }]
});

const User = mongoose.model('User', userSchema);

Python with PyMongo

from pymongo import MongoClient
import os

client = MongoClient(os.environ['MONGODB_URI'])
db = client['student_projects']
users = db['users']

# Insert a document
user = {
    'username': 'student123',
    'email': '[email protected]',
    'projects': []
}
users.insert_one(user)

Java with MongoDB Driver

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoDatabase;

String connectionString = System.getenv("MONGODB_URI");
MongoClient mongoClient = MongoClients.create(connectionString);
MongoDatabase database = mongoClient.getDatabase("student_projects");

Security Configuration

Network Access

• IP Whitelist your development machines
• VPN-friendly configuration for campus networks
• Temporary access for demonstration purposes
• 0.0.0.0/0 only for learning (never production)

Database Users

// Create application-specific users
// In Atlas UI: Database Access > Add New Database User
{
  username: "app-user",
  password: "secure-random-password",
  roles: [
    {
      role: "readWrite",
      db: "your-app-database"
    }
  ]
}

Connection Security

• Always use SSL/TLS connections
• Environment variables for connection strings
• Rotate passwords regularly
• Limit user permissions to minimum required

Advanced Features

Atlas Search (Full-Text Search)

// Create search index in Atlas UI
// Then query with aggregation pipeline
db.articles.aggregate([
  {
    $search: {
      index: "default",
      text: {
        query: "student projects",
        path: ["title", "content", "tags"]
      }
    }
  }
])

Charts and Analytics

• Create visualizations directly from Atlas
• Embed charts in web applications
• Real-time dashboards for application metrics
• Share insights with team members or professors

Change Streams (Real-time)

// Watch for changes in real-time
const changeStream = db.collection('messages').watch();
changeStream.on('change', (change) => {
  console.log('Database change detected:', change);
  // Trigger real-time updates in your application
});

Common Student Use Cases

Course Management System

// Collections structure
{
  courses: [
    {
      code: "CS101",
      name: "Introduction to Programming",
      instructor: "Dr. Smith",
      students: [ObjectId("..."), ObjectId("...")]
    }
  ],
  assignments: [
    {
      courseId: ObjectId("..."),
      title: "Final Project",
      dueDate: ISODate("2024-12-15"),
      submissions: [...]
    }
  ]
}

Social Media Application

// User posts with comments
{
  posts: [
    {
      userId: ObjectId("..."),
      content: "Working on my capstone project!",
      timestamp: new Date(),
      likes: [ObjectId("..."), ObjectId("...")],
      comments: [
        {
          userId: ObjectId("..."),
          text: "Looks great!",
          timestamp: new Date()
        }
      ]
    }
  ]
}

E-commerce Platform

// Product catalog with inventory
{
  products: [
    {
      name: "Student Laptop",
      category: "Electronics",
      price: 899.99,
      inventory: 50,
      reviews: [
        {
          userId: ObjectId("..."),
          rating: 5,
          comment: "Perfect for coding"
        }
      ]
    }
  ]
}

Performance Optimization

Query Optimization

• Use indexes for frequently queried fields
• Limit results with .limit() and pagination
• Project only needed fields with .select()
• Use aggregation pipelines for complex queries

Connection Management

// Connection pooling best practices
const mongoose = require('mongoose');

mongoose.connect(connectionString, {
  maxPoolSize: 10, // Maintain up to 10 socket connections
  serverSelectionTimeoutMS: 5000, // Keep trying to send operations for 5 seconds
  socketTimeoutMS: 45000, // Close sockets after 45 seconds of inactivity
  bufferCommands: false, // Disable mongoose buffering
  bufferMaxEntries: 0 // Disable mongoose buffering
});

Issue: “Connection timeout” errors
Solution:

• Check network/firewall settings
• Verify cluster is running
• Test with MongoDB Compass first

Performance Issues

Issue: Slow query performance Solution:

• Add appropriate indexes
• Use .explain() to analyze query execution
• Consider query optimization or schema changes
