Conceptual Database Design and Entity-Relationship Modeling

Designing a reliable database begins long before writing code or choosing a database engine. This course introduces you to conceptual database design, showing you how to model data logically using the Entity-Relationship model. You will build a strong foundation in database architecture that applies across any storage technology. What you will learn: Understand core database terminology, conceptual abstractions, and modeling principles. Define entities, attributes, candidate keys, and relationships accurately. Map one-to-one, one-to-many, and many-to-many entity connections. Apply basic normalization rules to ensure data consistency and reduce redundancy. Evaluate how conceptual models adapt to modern hybrid storage requirements like semi-structured data. Practice designing balanced schema structures through written step-by-step examples. Beginning with key definitions and fundamental concepts, the reading material walks you through real-world modeling scenarios from initial requirements to complete conceptual schemas. This beginner-friendly program requires no previous programming or database experience and is ideal for aspiring developers, data analysts, and IT professionals.
