Microsoft Power BI

Microsoft Power BI is a business analytics tool that visualizes data and enables its sharing. One of the most useful features of Power BI is that professionals can turn raw data into informative reports and dashboards. This way, businesses can understand important trends and, in turn, make informed and data-driven decisions. Power BI consists of a few components such as Power BI Desktop, Power BI Service, and Power BI Mobile. Each component serves a specialized purpose.

Key features of Power BI

With Power BI, users can connect to various data sources such as files, databases, cloud services, and APIs. The supported file formats are Excel, CSV, XML, and JSON. Power BI is compatible with SQL Server, Oracle, and MySQL, to name a few of the databases, and Azure, Salesforce, and Google Analytics as cloud services. With APIs, users can establish a custom connection between Power BI and data originating from web services.

Another feature of Power BI is data transformation. Once the data source is connected, users can modify the data by removing duplicates, filtering rows, and merging queries. In case there are different datasets, users can also use the feature data modeling to establish relationships between them. The supported data modeling features are Star Schema Modeling and DAX (Data Analysis Expressions). With Star Schema Modeling, users can simplify complex data relationships to increase overall performance. With DAX, users can use formula language to create custom calculations or measures.

Power BI's most prominent feature is visualization. The visualization types vary from simple to more advanced. The simple ones include bar, line, pie, and donut charts. For more complex visualizations, users can apply matrix visualization or custom visuals from the Power BI marketplace.

After creating the visualizations, users can share and collaborate on projects. These features are only available for Power BI Service.
