Syllabus

Module 1: Design Overview

This module is organized in three lessons: 1) Entity-Relationship (E-R) modeling, 2) E-R diagrams, and 3) Extended ER features and relation schemas. The learning objectives of this module are presented below. Refer to the enrichment activities at the end of each lesson.

Module 2: Functional Dependency (FD)

This module explores the theory and practical application of functional dependencies in relational database design, providing students with the knowledge and skills to identify and enforce data relationships, ensuring data integrity and optimization in database systems. This module is organized into three lessons: 1) Functional dependency theory, 2) Finding candidate keys and attribute closure, and 3) Deriving canonical (minimal) covers of functional dependencies. The learning objectives of this module are presented below. Please refer to the enrichment activities at the end of each lesson.

Module 3: Database Normalization

The database normalization module demonstrates the principles and techniques of organizing data into well-structured tables through normalization, ensuring data integrity and reducing redundancy for efficient and scalable database systems. This module is organized in three lessons: 1) Normal Forms (NFs), 2) more Normal forms, and 3) DB Design example (applying ER modeling + Normalization). The learning objectives of this module include are presented below. Refer to the enrichment activities at the end of each lesson.
