Lesson 3 • Protocols and the OSI Model

Covers the layered model of network communication and key protocols at each layer. Enables students to trace data flow and diagnose issues at specific network layers.

Lesson 4 • Internet Architecture and Web Technologies

Explains how the internet is structured and how web services operate. Connects networking theory to the real-world systems students interact with daily.

Lesson 1 • Relational Database Concepts

Introduces tables, keys, relationships, and normalisation principles. Establishes the theoretical foundation for designing well-structured relational databases.

Lesson 2 • Data Integrity, Backup, and Recovery

Covers transactions, ACID properties, backup strategies, and disaster recovery. Ensures students can maintain data reliability and continuity in production environments.

Lesson 3 • NoSQL and Non-Relational Databases

Introduces document, key-value, column-family, and graph database models. Expands students' ability to select the right database type for diverse application needs.

Lesson 4 • SQL Querying and Data Manipulation

Covers SELECT, INSERT, UPDATE, DELETE, and JOIN operations in SQL. Enables students to retrieve and modify data accurately in relational database systems.

Lesson 1 • Agile and Iterative Methodologies

Introduces Agile principles, Scrum, Kanban, and sprint-based delivery. Prepares students to work effectively in modern iterative development environments.

Lesson 2 • DevOps and Continuous Delivery

Introduces CI/CD pipelines, containerisation, and infrastructure automation. Connects development and operations practices to accelerate reliable software delivery.

Lesson 3 • Version Control and Collaboration

Teaches branching, merging, pull requests, and collaborative workflows using version control systems. Enables students to contribute to shared codebases without conflicts.

Lesson 4 • Software Testing and Quality Assurance

Covers unit, integration, system, and acceptance testing strategies. Builds the discipline to deliver reliable, defect-minimised software consistently.

Lesson 1 • Identity, Access, and Authentication

Teaches authentication methods, authorisation models, and identity management. Ensures students can design access controls that enforce least-privilege principles.
