Extensive library support for educational features
Strong community backing
Excellent documentation
Rapid development capabilities
Scalability for handling multiple concurrent users

Database Architecture

Primary Database: PostgreSQL or MySQL
Caching Layer: Redis
Search Engine: Elasticsearch
Considerations:
Implementation of efficient data modeling for course content
Optimization for quick retrieval of learning materials
Robust handling of user session data
Secure storage of assessment results and user progress

2. Frontend Development

Modern LMS platforms require intuitive and responsive user interfaces:

Core Technologies

Framework: React or Vue.js
State Management: Redux or Vuex
UI Components: Material-UI or Tailwind CSS
Benefits:
Single Page Application (SPA) capabilities
Smooth user experience
Responsive design for multiple devices
Real-time updates and interactions

Essential Features and Implementation

1. Authentication and Authorization

Implementation Stack:
