ER Diagrams and Database Design Foundations

Designing a robust database starts with a clear, logical blueprint, but translating complex real-world requirements into clean Entity-Relationship (ER) diagrams can feel overwhelming. This course simplifies database modeling, helping you master the core concepts needed for academic exams and real-world software engineering. Through clear written explanations, structured examples, and step-by-step design exercises, you will transition from a beginner to a confident database designer. You will learn how to analyze requirements, construct accurate ER models, and seamlessly convert those models into relational database schemas. What you'll learn: 1. Understand foundational database concepts, including entities, attributes, relationships, and keys. 2. Design accurate ER diagrams using standard notations. 3. Apply cardinality and participation constraints to represent real-world business rules. 4. Convert ER diagrams into normalized relational tables without losing data integrity. 5. Analyze complex database design scenarios commonly featured in computer science exams. 6. Practice mapping weak entity sets and multi-valued attributes to relational schemas. The course begins with essential database definitions and core ER diagram components before moving into advanced relationship constraints. You will then progress to practical schema mapping techniques and normalization strategies to ensure your designs are efficient and exam-ready. This course is designed for computer science students, exam candidates, and aspiring database administrators. No prior database design experience is required.
