The first method we will explore is the Direct Query. This method allows you to directly interact with the underlying data source within Power BI, removing the need to load your data into Power BI’s memory. Therefore, every time you create or interact with a visualization in your Power BI report, it formulates a query sent directly to the data source.
This approach is advantageous when dealing with large datasets that exceed Power BI’s one-gigabyte storage limit, maintaining real-time data freshness without frequent refreshing.
However, Direct Query also has limitations: DAX functionality is reduced; data transformation capabilities are limited; and performance might be reduced due to increased reliance on the source system’s capabilities.
Import
The ‘Import’ option is the most common method of loading data into Power BI. With this method, data is imported directly into Power BI’s internal memory. This allows faster calculations and analysis as compared to DirectQuery. Users can use all DAX functions and Power Query’s data transformation capabilities.
Though if the dataset size exceeds Power BI’s size limitations, users will need to either reduce the size or employ a different method. Updates are not automatic; reports have to be refreshed to reflect the most recent data.
Live Connection
The Live Connection method is similar to Direct Query but is leveraged when connecting to Analysis Services models. In this method, data remains in the original location, and queries are sent to the underlying dataset or database. This is optimal for large databases and enables real-time updates.
Like DirectQuery, the Live Connection method also has reduced DAX functionality, and you cannot utilize Power Query’s data transformation capabilities.
Composite Model
The last method we will discuss is the Composite model. It allows for the best of both worlds by permitting a mix of DirectQuery and Import within the same report. For instance, if you have a large dataset, you can use DirectQuery for that part of your data. Simultaneously, importing smaller datasets can optimize performance for calculations based on small sets.
Users should use Composite models carefully; the complexity of managing multiple data interaction methods may become challenging.
Concluding Thoughts
Making an informed decision about the appropriate data distribution method in Power BI requires a series of considerations. Factors like data size, performance requirements, data freshness requirements, and available transformations should always be evaluated. By having a thorough understanding of the benefits and drawbacks of each method, analysts could best align their decision with the reporting requirements.
