Power BI Tutorial for Beginners

Introduction

Power BI is a powerful analytics tool that allows organizations to glean insights from their data. This tutorial will demonstrate how to get started with Power BI, including how to import data, build a data model, create visuals, filter data, and share reports and dashboards with your team.

Getting Started with Power BI

To use Power BI, start by downloading it from the Microsoft Store. In the search bar, type in "Power BI," and you'll find three options:

Power BI: This allows you to view and interact with existing reports.
Power BI Desktop: This is the full-featured version for modeling data and building reports.
Report Builder: This contains similar functionalities to Desktop but lacks advanced features.

For this guide, we’ll use Power BI Desktop. Click to install or open it if you already have it installed.

Upon launching Power BI for the first time, you'll see a splash screen with options to get data, access recent sources, and view resources to help you learn. To skip the splash screen in future launches, uncheck the box at the bottom.

Importing Data

After closing the splash screen, you’ll enter the main report view. To import data, click on the “Get Data” option either from the left side or the Home tab on the ribbon. The dropdown will reveal numerous data sources. For this tutorial, we'll use an Excel workbook. Double-click your workbook to open the Navigator, where you can select the tables or sheets you want to import.

After selecting from your workbook, you can either load the data directly or choose to transform it first. Transforming data allows you to clean and modify it before bringing it into Power BI, which is especially useful if you don’t have permissions to edit the original data source. For now, select "Load."

Data Model and Transformations

Once you've loaded the data, you’ll see the imported tables on the right side. Click the Data View button to examine the customer data. If inconsistencies are found (like different terms for the same country), you can transform the data by clicking on the transform button on the Home tab.

The Power Query Editor appears, allowing you to make changes. For instance, you can right-click on a column to replace values or remove unnecessary columns. Once the data looks satisfactory, click “Close & Apply.”

In the Model View, Power BI detects relationships between tables (like Customer ID in both tables). If it doesn't automatically detect a relationship, you can manually create one by dragging fields from one table to another.

Creating Reports

Return to the Report View to start creating visuals. Here, you can drag and drop fields from your data tables into various visualization formats. For instance, a line chart can display cookies shipped over time, and a card visualization shows total revenue.

You can customize visuals by formatting options, adjusting titles, colors, and more. By clicking on table visualizations, you can filter charts based on selected entries, allowing for a detailed analysis by specific customers.

To add more pages for different data views, double-click on the current page to rename it or click the "+" icon.

Sharing Reports

Once your report is ready, you can share it with your team. Click the “Publish” button in the top right corner; you’ll need to save any changes first. Choose your destination workspace and publish your report.

After publishing, you can access it within the Power BI web service. Here, you can share it via email, generate a QR code, export it to PowerPoint or PDF, and even embed it into a SharePoint site or Microsoft Teams chat.
