What is Power BI?

Power BI is a business analytics tool used to analyze data and share insights. It is used to transform raw data into interactive dashboards and reports, making it easier to understand complex datasets. Power BI can connect to various data sources, including Excel spreadsheets, cloud services like Azure, AWS, Google Cloud, and on-premises databases, providing a flexible solution for data analysis and making it widely used in the industry.

Key Components of Power BI

Power BI has some core components that work in conjunction to offer an overall experience of data analysis.

• Power BI Desktop: It is a Windows application that is used to create reports and dashboards. It offers a friendly interface for data modeling, visualization, and report building.
• Power BI Service: This is an online SaaS-based service that enables users to publish and share reports and dashboards. It allows for collaboration with shareholders and team members and provides access to reports from anywhere.
• Power BI Mobile: It is an application available on both iOS and Android that enables mobile access to reports and dashboards while on the move.
• Power BI Gateway: It can be defined as a bridge that helps to transfer data from on-premises data sources to the Power BI service securely.
• Power BI Report Server: It is a hybrid solution that allows users to publish Power BI reports and traditional paginated reports in on-premises servers.
  

Starting with Power BI

Below are the steps to start with Power BI, for users who are new to Power BI can follow these steps;

Step 1. Download Power BI Desktop.

• If you are a new user of Power BI, download Power BI Desktop from here or from the official Microsoft website.
• Installation is simple & straightforward, and once installed, you can launch the application to get started exploring the features.
  

Step 2. Connect to Data Sources.

• With Power BI, we can connect to data sources. We have the option to connect a data source using the "Get Data" icon that is present in the Home ribbon.
• There are various options available, which include Excel, SQL Server, SharePoint, and many more.
• Once connected, the dataset can be loaded to Power BI for use in the next steps of analysis.
  

Step 3. Transform and Model Data.

• After loading the data, we may need to clean and transform it before using it to create visuals and perform analysis.
• Power BI has an extremely powerful data transformation tool called Power Query, which allows us to perform various complex operations, including filtering, merging, and aggregating data.
• Click on the Transform Data icon that is present in the Home ribbon.
  

Step 4. Create Visualizations.

• Once the data is loaded and transformed, we can start creating the visualizations.
• Power BI offers a variety of visualization types, including but not limited to bar charts, line graphs, pie charts, maps, and much more.
• Visualizations can be created by simply dragging and dropping fields from the dataset onto the report canvas.
  

Step 5. Build Reports and Dashboards.

• Once the visuals are created, they can be arranged into reports and dashboards.
• A report consists of multiple pages with visualizations, text, and data to present data in an easy-to-understand way, whereas a dashboard is one page with an overview of certain key metrics.
• The layout and the design of the reports and dashboards can be customized to our needs.
  

Step 6. Publish and Share.

• Finally, we can publish the reports and dashboards that we have created to Power BI Service to share the insights with our colleagues and stakeholders.
• We can also configure scheduled refreshes to ensure that data is always up-to-date.
