A3.2 Database design

All knowledge base resources related to A3.2 Database design.

This section focuses on the principles and practices of relational database design, emphasizing how to structure data effectively for accuracy, efficiency, and scalability. Students will learn how to describe database schemas, construct entity-relationship diagrams (ERDs), and select appropriate data types. They will develop skills in building relational tables, understanding normalization up to the third normal form (3NF), and evaluating when denormalization may be appropriate to improve performance in real-world scenarios.
