Relational Database Design and Data Modeling Fundamentals

Behind every powerful application lies a well-structured database. Without solid database design, even the best code can suffer from slow performance, data duplication, and severe maintenance headaches. This text-only course guides you through the entire database design lifecycle, from gathering business requirements to writing physical database scripts. You will learn how to think like a data architect, structuring information logically to ensure data integrity, system efficiency, and scalability. What you'll learn: - Understand core relational database concepts, including tables, primary keys, and foreign keys. - Design conceptual and logical data models using Entity-Relationship Diagrams (ERDs) based on real-world business scenarios. - Master database normalization rules from first to third normal form to eliminate data redundancy and anomalies. - Write clean SQL scripts to translate your logical designs into physical database tables. - Compare relational modeling with modern NoSQL document structures and understand when to use semi-structured data like JSON columns. You will begin with foundational terminology and conceptual modeling before moving on to normalization techniques and physical implementation. Through clear written explanations and practical design scenarios, you will build a solid foundation in data architecture. This course is designed for absolute beginners, aspiring developers, and data analysts with no prior database design experience. Start building a strong foundation for your data-driven career today.
