Introduction
Welcome to Unit 4. In this unit, you will develop the server-side functionality required for a fully functional eLearning application. You will implement CRUD operations, apply secure coding practices to protect user data, manage file uploads, and integrate automated email or SMS notifications. By the end of the unit, you will be able to build secure, dynamic, and interactive web applications that support effective online learning.
Intended learning outcomes
- Implement full CRUD (Create, Read, Update, Delete) operations for user management and course management in a web-based eLearning application.
- Apply secure coding practices, including password hashing, prepared statements, input validation, and session management, to protect the application against common web vulnerabilities.
- Develop functionality for uploading and serving files (images, videos, PDFs, and SCORM packages) within an eLearning system.
- Implement automated email or SMS notification functionality using a server-side email library or API.
-
Before participating, review the unit materials on secure programming practices for educational web applications.
When responding:
- Write clear, original answers based on your understanding and experience.
- Explain concepts with relevant examples rather than only providing definitions.
- Engage with at least one classmate’s post by offering a new insight, asking a thoughtful question, or presenting an alternative perspective.
- Use appropriate technical terminology and maintain a professional, respectful academic tone.
1. Imagine you are developing a university learning management system. What measures would you implement to protect student and lecturer accounts? Explain why these measures are important.
2. A student uploads an assignment file to an online learning platform. What security considerations should developers apply when handling uploaded files? Explain why storing files safely is important.
