Power BI provides multiple storage modes to balance performance and real-time data requirements.
| Storage Mode | Description |
|---|---|
| Import | Data is loaded into Power BI memory for maximum performance. |
| DirectQuery | Queries data directly from the source system. |
| Dual | Acts as both Import and DirectQuery. |
| Direct Lake | Reads data directly from OneLake without importing. |
Architect Recommendation: Use Import whenever possible for performance and DirectQuery only when real-time data is required.
