If you do not comply with Power BI Performance best practices, then your dashboards will no longer be effective - making your visuals and reports slow, and cluttered. This eventually diminishes the value of your data analysis effort.
So, hereās the big question: What are the best practices for using Power BI effectively?
To answer this, we have brought the top best practices for effective Power BI usage, which helps you simplify and make your report more efficient.
Meanwhile, look at the expert discussion held on Reddit, and see what experts are saying about Power BI performance tuning.
Here are the top best Practices for effective Power BI usage, which will help you simplify and optimize your report.
When was the last time you checked if your data model is slowing things down? A well-optimized data model makes your Power BI reports run smoothly.
Here's how you can do it:
Using Star Schema:
It is always worth using start schema in your Data Modeling. Because it improves performance and the results you get are accurate. Think of a star schema like a railway hub. All data flows through a central station (fact table) and connects to different stations (dimension tables), making analysis efficient.
In fact, this is one of the main reasons why professionals switch from Tableau to Power BI.
Reducing query load is like giving your system a breather, making it perform well under pressure. Here's how to optimize the load:
Reducing Data Load:
Filtering Data at Source:
Use SQL queries to limit the data fetched from the database.
Reducing Data Load:
By managing the above aspects, you can optimize Power BI reports for better efficiency.
Have you ever been stuck waiting for a report to load because the data refresh was slow? I'm sure you have, right? Managing data refresh properly ensures your reports are always up to date without delays.
Hereās how you do Power BI Performance tuning.
Handling Large Datasets:
Break down large datasets into smaller chunks. Itās like splitting a large task into smaller onesāeasier to handle and process.
Check out what modeling experts on Reddit have to say about Data Modeling - One Large Dataset or Several Smaller Datasets?
Have you ever wondered why your DAX formulas take so long to calculate? Itās usually because they arenāt optimized. Getting DAX right makes your reports faster and smoother.
