With its intuitive interface, you can craft customized and insightful reports.

Power BI Service

Power BI Service, also known as Power BI online, is the cloud-based platform where you can publish, share, and collaborate on your Power BI reports and dashboards. It allows you to securely store your reports in the cloud, making them accessible from anywhere with an internet connection. Power BI Service also offers features like automatic data refresh, sharing controls, and collaboration tools, enabling teamwork and real-time decision-making.

Power Query Editor

Power Query Editor is an integral part of Power BI Desktop. It is used for data transformation and preparation. With Power Query, you can connect to various data sources, filter and clean data, pivot and unpivot tables, merge and append queries, and perform numerous other data shaping operations. Power Query ensures that your data is accurate, consistent, and ready for analysis.

Data Sources

To work with Power BI, you need access to the data you want to analyze. Data sources can include databases (SQL Server, Oracle, MySQL, etc.), spreadsheets (Excel, CSV), cloud services (Azure, AWS, Google Cloud), web-based APIs, and more. Power BI’s ability to connect to diverse data sources is a key strength, enabling you to gather data from multiple places for comprehensive analysis.

Microsoft Account

To use Power BI, you’ll need a Microsoft account, often associated with services like Outlook, Office 365, or Azure. This account is used to sign in to both Power BI Desktop and Power BI Service. It’s essential for accessing your reports, sharing content, and collaborating with others. You can create a free Microsoft account if you don’t already have one.

DAX (Data Analysis Expressions)

Data Analysis Expressions (DAX) is a formula language used in Power BI (as well as other Microsoft products like Excel and Analysis Services). DAX allows you to create calculated columns and measures within your data model. These calculations can be simple aggregations or complex formulas, enabling you to perform advanced data analysis and build meaningful KPIs (Key Performance Indicators).

Power BI Mobile App

The Power BI Mobile App is available for various devices, including smartphones and tablets. It allows you to access your Power BI reports and dashboards while on the go. This is particularly useful for staying informed and making decisions when you’re not at your desktop. The mobile app offers interactive capabilities, ensuring that you can explore and interact with your data even on a smaller screen.

Power BI Gateway

For organizations that have on-premises data sources (data stored locally within your organization’s network), Power BI Gateway is a crucial tool. It acts as a bridge between your local data and the Power BI Service in the cloud, allowing you to schedule data refreshes and ensure that your reports reflect the most up-to-date information.

Custom Visuals and Extensions

While Power BI offers a wide range of built-in visuals, you can expand your options by using custom visuals and extensions developed by the Power BI community and third-party vendors.
