Introduction – What is Power BI?

Power BI is a synchronous collection of services, apps, and connectors. They combine to turn your unrelated data sources into valuable, visually immersive, and interactive insights. It is an essential tool in a data analysts toolkit, and today we'll learn about Power BI training for beginners.

 

Power BI DAX 

Data Analysis Expressions collect various constants, functions, and operators to select BI and data visualization tools. It is called function language because the entire code resides inside the parts.

DAX allows users to create new information from data that already exists in your model. It can be manipulated to help define the custom calculations used in calculated columns and fields. It also helps in performing dynamic aggregation and working with relational data. DAX allows flexibility for data models but can get complicated. However, it has a steep learning curve.

 

The Amazing Power BI

Power BI is versatile and loaded with features; professionals in many different roles use it, including:

  • Administrators
  • Professionals (accountants, sales professionals, marketers)
  • Designers
  • Developers

But any role at any company could find a valid and valuable use of Power BI. The features available to Power BI users ensure that it is a useful tool for all. 

Power BI facilitates intelligent decision-making, reducing the likelihood of failure and mitigating risks. The data processed by BU are available for interaction 24/7, anywhere you have mobile access. This convenient feature allows users to pull, process, and share real-time data anytime, anywhere. It is easy to use, gives access to over 70 data connectors, and allows data sharing and collaboration.

Because of the existence of never-before-seen levels of data today, Power BI is a powerful tool to make informed decisions. Harness the power of your data through interactive and visually engaging graphs produced by Power BI.

Power BI Service

The Microsoft Power BI service (app.powerbi.com) or Power BI online is SaaS (Software as a Service) or cloud. Dashboards and reports connect to datasets that bring all of the relevant data together in one place. Dashboards display tiles; we can select to open reports for further exploration. 

Mobile apps

BI is available on mobile phones (Android and IOS). Power BI offers a set of applications for iOS, Android, and Windows. We can connect to and interact with the cloud and on-premises data. We can also use Power BI Desktop, the service, and the mobile apps to create, share, and consume business insights. Read What is Power BI for an overview. 

Power BI Report Server

Users can connect to the desired sources and build reports using the Power BI Desktop. When the report is complete, users publish it to the Power BI service, allowing end-users to view and interact with the information. You can use the Power BI Report Server if you want to keep the privacy of reports to company personnel. After you create your Power BI reports using Desktop, you can publish them to an on-premises report server.

Components of Power BI

Power Query transforms the data enabling us to discover, connect, combine, and refine data sources to meet our analysis needs. It is downloadable as an add-in for Excel or used as part of the Power BI Desktop.

Power Pivot is a data modeling method that helps create data models, establish relationships, and make calculations. It uses DAX language to model simple and complex data.

Power View is available in MS Excel, PowerBI, Sharepoint, and SQL Server. It allows you to create interactive charts, graphs, maps, and other visuals that bring your data to life. It also connects data sources and filters data for each data visualization element or the entire report.

MS Power Map works with Bing maps to get 3D visualization based on information on latitude, longitude, country, state, city, and street address.
