What you'll learn

Organizations struggle to organize their data in ways that both reflect business reality and support technical implementation. Without proper data modeling, systems become fragmented, inconsistent, and difficult to maintain. In this course, Conceptual and Logical Data Modeling, you'll gain the ability to translate business requirements into structured data designs. First, you'll explore how to create conceptual models that capture business entities, attributes, and relationships using entity-relationship diagrams. Next, you'll discover how to transform conceptual models into logical designs with proper tables, columns, keys, and constraints. Finally, you'll learn how to evaluate and refine logical models for accuracy, completeness, and readiness for implementation. When you're finished with this course, you'll have the skills and knowledge of conceptual and logical data modeling needed to bridge business requirements and technical implementation.
