What are some effective case studies for SQL Server data modeling?

There are several notable case studies that showcase effective SQL Server data modeling. For instance, a retail company improved its inventory management by implementing a star schema, which streamlined reporting and analysis.

Can you explain how the star schema works in that context?

Sure! A star schema organizes data into fact tables and dimension tables. In the retail case, the fact table might contain sales data, while dimension tables could include product details, store locations, and time periods, making queries more efficient.

What other data modeling techniques are commonly used?

Other common techniques include snowflake schemas, normalization, and denormalization. Each has its own advantages depending on the specific use case.

Can you provide an example of normalization in SQL Server?

Absolutely! Normalization involves organizing data to reduce redundancy. For example, instead of storing customer information in every order record, you would create a separate customer table and link it to the orders table using a foreign key.
