Online Services: Connect to platforms like SharePoint, Salesforce, and Google Analytics.  
 
Steps to connect to a data source:  
 
1. Firstly Click the “Get Data” button on the Home tab.  
 
2. Choose your data source from the list and follow the prompts to connect. For example, if you select “Excel,” you’ll need to locate and select your Excel file.  
 
3. Once connected, you can preview your data and perform data transformations if needed. 

   

 

2.4 Data Transformation  
 

Data transformation is a crucial step in the Power BI development process. It involves cleaning, shaping, and structuring your data to make it suitable for analysis. Power BI gives a range of data transformation tools, as well as:  
 
Data Cleaning: To Remove duplicates, handling missing values, and rectifying data errors.  
 
Data Shaping: Pivoting, unpivoting, and transforming data structures.  
 
Merging and Combining Data: Combining data from multiple sources to create a unified dataset.  
 
Data Modelling: Defining relationships between tables to establish data hierarchies.  
 

 
2.5 Creating Visualizations  
 

With your data loaded and transformed, it’s time to create visualizations. Visualizations are graphical representations of your data that make it easier to understand and analyse. Power BI offers a wide array of customizable visuals, including:  
 
Charts: Different types of pie charts, bar charts, line charts, etc.  
 
– Tables: Tabular representations of data.  
 
Maps: Geographic visualizations for location-based data.  
 
Cards and KPIs: Single-value display for critical metrics.  
 
 
To create a visualization:  
 
1. In the “Fields” pane on the right, drag and drop data fields onto the report canvas.  
2. Customize your visuals by formatting, resizing, and adding titles and labels.  
 
 

2.6 Building Your Report  
 

Creating a comprehensive report involves more than just individual visuals. You’ll want to build a cohesive narrative that tells a data-driven story. Here are some steps to consider:  
 
Page Layout: Use the report pages to organize your visuals logically. You can add multiple pages to create a structured report.  
 
Filters: Implement interactive filters that allow users to explore the data dynamically.  
 
Text Boxes and Images: Enhance your report with text boxes, images, and explanations to provide context to the data.  
 
 
 

2.7 Saving and Publishing  

Once you’ve created your Power BI report, it’s essential to save your work and consider sharing it with others. Here’s what to do:  
 
 
1. Save your Power BI report by clicking on the floppy disk icon or pressing `Ctrl + S.` Save it in your preferred location.  
 
2. To share your report with others, you can publish it to the Power BI service, Microsoft’s cloud-based platform for sharing and collaborating on reports and dashboards. Click on the “Publish” button.  
 
3. Sign in with your Microsoft account to upload your report to the Power BI service.
