Unlock the power of Data with Microsoft Power BI - 8 tips 🚀
Hello there,
My name is Dennis, and in this blog post I want to teach you a thing or two about Microsoft Power Bi. Because in today's data-driven world, businesses all over the world rely on insights to make informed decisions. Microsoft Power BI is a powerful tool that can help you turn your raw data into meaningful information. In this easy-to-read blog, we'll explore some key aspects of Power BI to help you on your way to become a true data hero.
Tip 1: Data cleaning: The foundation of high Quality Data
Before you dive into creating stunning reports, it's essential to ensure your data is clean and accurate. Power BI’s data cleaning capabilities, powered by Power Query, make this process a breeze. You can e.g.:
Remove duplicates: Eliminate redundant data entries to maintain data integrity.
Filter and sort: Easily organize your data to focus on what's relevant.
Handle missing data: Fill in gaps or remove incomplete records to avoid skewed insights.
These are just some examples to get you going. Be curious and explore the power query editor.
The column quality, distribution and profile capabilities are useful tools to get a grip on the data quality of your source data.

Tip 2: Data Modelling: Building a Solid Framework
Data modeling in Power BI is like creating a roadmap for your data. It involves defining relationships between different data tables to extract valuable insights. I would strongly encourage you to have a look at ‘Kimball modeling’. In case you don’t know this concept. It is in summary a dimensional modeling approach that is focused on creating data tables optimized for query performance, user-friendliness, and consistency. It employs star or snowflake schema designs, conformed dimensions, and hierarchies to provide a solid foundation for business intelligence and analytics.
Key steps include:
Defining relationships: Establish connections between tables using primary and foreign keys.
Creating calculated columns: Generate new data based on existing values using simple expressions.
Writing DAX measures: Use Data Analysis Expressions to calculate complex aggregations and metrics.
Tip 3: Choose the Right Visuals: Less is More
Remember, the goal is to make your data easy to understand. Choose the right visualization type for your data to avoid confusion. For example, use a line chart for sales trends over time, not a pie chart.
Creating effective data visualizations is both an art and a science. Follow these best practices to enhance the impact of your visualizations:
Use Appropriate Visuals: Select the right type of visualization for your data and the story you want to tell. Avoid overloading visuals with unnecessary details.
Colour Choices: Employ a consistent and meaningful colour scheme to convey information. Consider using colour-blind-friendly palettes for accessibility.
Labels and Titles: Include clear labels, axis titles, and chart titles to help viewers understand your visualizations without ambiguity.
With your data cleaned and structured, it's time to visualize it. Power BI offers a wide range of visualization options to convey insights effectively:
· Bar Charts: Compare data points easily using bars of varying lengths.
· Line Charts: Visualize trends and patterns over time.
· Pie Charts: Show proportions and percentages at a glance. Use maximum 5 categories.
· Maps: Plot geographical data to uncover regional insights.
· Tables and Matrices: Display detailed data in a structured format.
Let’s also take a moment to stand still at themes. Because it’s important that your business reports all have the same look and feel. The theme is a predefined collection of settings that define the visual appearance of a Power BI report. Themes allow you to maintain a consistent and branded look for your reports by specifying colors, fonts, and other formatting options.
Tip 4: Interactivity: Engage Your Audience
Power BI lets you add interactivity to your reports, making them more engaging:
Filters: Allow users to focus on specific data subsets.
Slicers: Create interactive sliders to refine data views.
Buttons: page and bookmarks buttons allow you to interact in a more intuitive way.
Drill-through: Enable users to explore details by clicking on visuals.
Try to add these elements in a Web-like UX. By using on hover designs like the tooltip to show extra information. Adding the visual pages button and a toggle enhances the web-like feeling of your users.
Tip 5: Don’t be afraid to use external tools
Excel: How could I start with anything else right? Excel is a natural companion to Power BI. You can use Power Query in Excel to transform and clean data, and then import that data into Power BI. Additionally, you can use Excel as a data source within Power BI.
GitHub: Collaborate with your team on Power BI projects by using version control tools like GitHub. It helps manage changes and track history. Note that you need to save your report as Power BI Project (PBIP) file for this. When saving as a project, report, and dataset definitions are saved as individual plain text files in a simple, intuitive folder structure.

DAX Studio: DAX Studio is a third-party tool that provides advanced capabilities for writing, testing, and optimizing Data Analysis Expressions (DAX) code used in Power BI.
Tabular Editor: This tool allows for advanced editing and managing of Tabular models, which can be especially useful when working with large and complex datasets.
Tip 6: Sharing Insights: Collaborate and Empower Decision-Making
Once you've created insightful reports and dashboards, it's time to share your findings with others. Power BI offers various sharing and collaboration options to ensure effective decision-making:
Publish to the Web: Share your interactive reports publicly by publishing them to the web, enabling broader access.
Power BI Service: Your published reports are hosted on the Power BI Service, where users can access, interact with, and collaborate on reports in a secure cloud environment.
Embed Reports: Embed Power BI reports directly into websites, applications, or SharePoint to ensure seamless access for users.
If you’re collaborating on a report in a small development team it is worth noting that there is OneDrive and SharePoint integration available. This way you can use the version control from SharePoint to restore your report to a previous point. Also, with the Share button at the top right of the screen you’ll be able to use standard SharePoint and OneDrive UI to get a shareable link or send it to the people who need it.
