Problem

Context

Dimensional modeling choices affect how easily analysts can query data and how efficiently a warehouse supports reporting. In a sales environment such as Coca-Cola Consolidated reporting, this often comes down to choosing between a star schema and a snowflake schema.

Core question

You are asked to explain the difference between a star schema and a snowflake schema. Describe how fact tables and dimension tables are organized in each model, what role normalization plays, and how those choices affect query simplicity, storage, maintainability, and performance.

Scope guidance

A strong answer should define both schemas clearly, compare them directly, and explain when you would choose one over the other in a practical analytics setting. You should also mention common trade-offs rather than treating one model as universally better.
