Relational Database Design: Functional Dependency and Normalization

Designing an efficient database requires more than just creating tables; it demands a deep understanding of how data fields relate to one another. Without proper structure, databases suffer from redundancy, update anomalies, and performance bottlenecks. This text-based course guides you through the foundational concepts of functional dependencies and database normalization. You will transition from basic data organization to designing highly structured, optimized relational databases, preparing you for both real-world software engineering challenges and technical database exams. What you'll learn: - Understand the core definitions of functional dependency and how data attributes interact. - Identify different types of functional dependencies, including full, partial, and transitive dependencies. - Apply normalization rules step-by-step from First Normal Form (1NF) up to Boyce-Codd Normal Form (BCNF). - Solve practical database design problems and practice with exam-style schema analysis questions. - Evaluate the trade-offs between normalized and denormalized structures in modern application development. - Determine candidate keys and find minimal covers for any database schema. The course begins with essential database terminology and foundational definitions before moving into step-by-step normalization techniques. You will read through clear explanations, analyze structured data schemas, and work through practical design scenarios. This course is designed for beginner database developers, computer science students, and anyone preparing for technical database examinations. No prior database design experience is required.
