Module Artifacts
This file outlines the topics covered in the module—including 3NF limitations, BCNF definition and violation detection, comparisons between normal forms, and higher normal forms such as 4NF and 5NF—serving as a navigational overview for learners and instructors to understand the module's scope and sequence.
A slide deck covering advanced normalization beyond 3NF — including BCNF, 4NF, and 5NF definitions, motivations, and decomposition strategies — used by instructors to deliver the module's core lecture content.
A reading that explains the formal definition of 3NF, its role in eliminating common redundancy and anomalies, and the specific limitations (such as anomalies caused by overlapping candidate keys) that motivate stricter normal forms; learners read it as foundational context before studying BCNF.
A reading that defines Boyce-Codd Normal Form, explains how it tightens 3NF by requiring every functional dependency's determinant to be a superkey, and walks through examples of detecting and correcting BCNF violations; learners use it to understand when and how to apply BCNF decomposition.
A reading that directly compares 3NF and BCNF — their definitions, the scenarios where they differ, the trade-offs between lossless decomposition and dependency preservation, and guidance on choosing between them; learners use it to decide which normal form is appropriate for a given schema.
A reading that introduces multivalued dependencies, explains why BCNF cannot detect the redundancy they cause, defines Fourth Normal Form (4NF), and demonstrates how to decompose relations to eliminate multivalued dependency violations; learners use it to extend their normalization skills beyond functional dependencies.
A reading that introduces join dependencies, explains why 4NF cannot address the redundancy they produce, defines Fifth Normal Form (5NF / Project-Join Normal Form), and illustrates how to identify and decompose relations with non-trivial join dependencies; learners use it to understand the most advanced standard normalization level.
A reading that walks through end-to-end case studies of normalizing complex, real-world-style schemas through 3NF, BCNF, 4NF, and 5NF in sequence, offering practical decision-making guidance for each step; learners use it to practice applying all higher normal forms together on multi-table schemas.
