What is model simplification strategy?

< 1 min read

Model simplification strategy means reducing complexity to improve performance and usability.
In one project, we removed unused columns and tables from the data model.
High-cardinality columns not required for analysis were excluded.
We replaced calculated columns with measures where possible.
Many-to-many relationships were replaced with bridge tables to reduce ambiguity.
Aggregated tables were created for large fact tables to speed up visuals.
We also limited page-level visuals to only key KPIs.
Overall, simplification improves refresh time, query speed, and user experience.
