Introduction

In this article, we will explore the step-by-step process of building Power BI reports. Power BI is a powerful business analytics tool that allows users to Visualize and share insights from data. We will cover both Power BI Desktop, which is the free modeling tool for authoring reports, and Power BI Service, which is the online portal for publishing and sharing reports.

What is Power BI?

Power BI is a business analytics tool that enables users to get data from multiple sources, model it, and Create interactive reports and dashboards. It offers a range of features, including data visualization, data modeling, and collaboration capabilities. With Power BI, users can gain insights from their data and share them with others.

Power BI Desktop

Power BI Desktop is the free modeling tool for authoring reports. It includes two main components: Power Query and Power Pivot. Power Query allows users to get data from a variety of sources and clean and transform it before loading it into the data model. Power Pivot enables users to model the data and create calculated measures.

Power Query

Power Query is a data transformation and integration technology that allows users to discover, combine, and refine data from a variety of sources. With Power Query, users can easily connect to data from databases, files, and online services, and perform various transformations such as filtering, sorting, and aggregating the data.

Power Pivot

Power Pivot is an in-memory data modeling component that allows users to create relationships between tables, define hierarchies, and calculate measures. With Power Pivot, users can create complex data models that can handle large amounts of data and perform advanced calculations and analysis.

Loading Data

In Power BI Desktop, users can load data from various sources such as databases, files, and online services. They can connect to these sources using Power Query and import the data into the data model. Power BI supports a wide range of data sources, including Excel, SQL Server, SharePoint, and Salesforce.

Creating Relationships

Once the data is loaded into the data model, users need to define relationships between the tables. Relationships are used to link the data in different tables Based on common fields, and they enable users to create powerful visualizations and calculations that combine data from multiple tables.

Creating Calculated Measures

In Power Pivot, calculated measures are used to perform calculations on the data. Users can create measures using the DAX (Data Analysis Expressions) language, which is a formula language similar to Excel formulas. Calculated measures can be used to calculate sums, averages, percentages, and other aggregations based on the data in the tables.

Power BI Service

Power BI Service is the online portal for publishing, sharing, and collaborating on Power BI reports and dashboards. It allows users to view and Interact with reports from any device with an internet connection. Power BI Service offers a range of features, including data refresh, sharing, collaboration, and security and access control.

Publishing Reports

In Power BI Desktop, users can publish their reports to the Power BI Service. Publishing reports makes them accessible in the cloud, and users can view and interact with them in the Power BI Service. To publish a report, users need to sign in to their Power BI account, choose the destination workspace, and click the publish button.

Sharing Reports and Dashboards

Once a report is published to the Power BI Service, users can share it with others. Sharing allows users to collaborate on reports and dashboards, and control who can view and edit them. Users can share reports and dashboards by entering the email addresses of the recipients, and they can specify the level of access each recipient has.

Refreshing Data

To ensure that the data in their reports is up-to-date, users can refresh the data in Power BI. Data refresh retrieves new data from the data sources and updates the reports and dashboards. Power BI supports both manual and scheduled data refresh. Manual refresh allows users to update the data on-demand, while scheduled refresh automatically updates the data at specified intervals.

Security and Access Control

Power BI offers various security and access control features to protect data and ensure that it is accessible only to authorized users. Users can control who can view and edit reports and dashboards, and Apply row-level security to restrict data access based on user roles. Power BI also supports encryption and multi-factor authentication for added security.

Conclusion

Power BI is a powerful business analytics tool that allows users to visualize and share insights from their data. With Power BI Desktop, users can create reports and dashboards by loading data, creating relationships, and performing calculations. Power BI Service enables users to publish and share their reports, refresh the data, and collaborate with others. By using Power BI, users can gain valuable insights from their data and make informed decisions.
