Relational Database Design with ER Modeling and Normalization

Every robust software application relies on a well-structured database, yet poor database design is one of the leading causes of application performance bottlenecks. Understanding how to structure your tables, relationships, and constraints correctly from the start saves countless hours of refactoring later. This text-based course guides you through the entire database design lifecycle, from initial conceptual planning to a fully optimized physical schema. You will gain the practical skills needed to design clean, efficient, and anomaly-free relational databases for any application. What you'll learn: - Understand foundational database concepts, primary/foreign keys, and relational constraints. - Build clear Entity-Relationship (ER) models to map real-world business requirements. - Apply normalization techniques up to Third Normal Form (3NF) to eliminate data redundancy. - Transform conceptual ER models into structured physical table schemas. - Implement basic indexing strategies and schema migration concepts to ensure long-term performance and maintainability. You will start by mastering core relational concepts and terminology before moving step-by-step through modeling, normalization rules, and physical implementation details. Detailed written explanations and practical design scenarios ensure you can confidently apply these structural principles to your own software projects. This course is designed for absolute beginners, aspiring developers, and data analysts who want to build a strong foundation in database architecture without any prior design experience.
