How can you optimize your dimensional model for reporting?
Dimensional modeling is a widely used technique for designing data warehouses and data marts that support reporting and analysis. A dimensional model consists of a central fact table that stores quantitative measures and related dimension tables that store descriptive attributes. However, not all dimensional models are equally efficient and effective for reporting purposes. In this article, you will learn some tips and best practices to optimize your dimensional model for reporting.
-
Select appropriate granularity:Tailor the detail level of your fact tables to meet specific reporting needs. This ensures flexibility and accuracy without overwhelming your data storage.### *Normalize your dimensions:Organize dimension tables to eliminate redundancy and ensure consistency. This enhances data quality and simplifies updates, making your reports more reliable.
