About the Course
Data modeling interviews test whether you can design schemas that balance query performance, data integrity, and evolution. This course gives you a repeatable framework: gather requirements, design conceptual and logical models, optimize physical storage, and plan for scale and schema evolution.
Start with The Modeling Playbook — an interview framework tailored to data modeling roles, schema design trade-offs, and a guide to choosing the right storage pattern. Then build your vocabulary with 12 concept lessons covering normalization, dimensional modeling, SCDs, fact tables, data vault, temporal modeling, and more.
Finally, practice with 14 end-to-end design cases — from e-commerce order systems to real-time analytics dashboards — each with ER diagrams, CREATE TABLE statements, and leveled expectations showing what separates mid-level from staff-level answers.
