Learn Power BI online
What is Power BI?
Microsoft’s Power BI is an application suite that allows users to import data in various forms from many sources and transform that data into a variety of visualizations, making business information easier to communicate and business decisions easier to make.Footnote 1 The many applications of Power BI make it a popular choice for those involved in business intelligence, the field in which professionals use various strategies and technologies to manage and analyze data.Footnote 2 For example, with Power BI, an analyst can take data from social media, customer reviews and purchase histories, and transform that information into visualizations that can help a company figure out which of its products are bestsellers and which are duds.Footnote 3
Power BI lets users import both structured data, which is data that conforms to a predefined data model or format, and unstructured data, which is data in its raw form.Footnote 4 That gives Power BI the ability to simultaneously work with structured data like product names and times of day, and unstructured data, like video. Using both types of data in this way, Power BI can allow a store to track how quickly stock of certain items sell out and even study how soon into a shopping trip someone picks up a particular product. Data sources for Power BI can range from data stored on the cloud, on-premise (meaning in a server in a private facility), scraped off the internet, from programs like Excel or Google Sheets, and more, extending the many possible applications of Power BI.Footnote 5
Power BI’s three components allow access to the suite using a variety of avenues. Power BI Desktop and Power BI Mobile allow access to Power BI on either desktop or mobile devices. Power BI Service, a software as a service (SaaS), allows users to interact with the visualizations created by Power BI on the cloud.Footnote 6
Power BI is powerful enough that it even allows users to browse visualizations using natural language, meaning that someone can type a question into Power BI using the same phrasing one would use when speaking to a person. Power BI can then search through its library of visualizations and data to see what answers can be found.
Regardless of the industry, workers can find many uses for this tool. And for those interested in unlocking these opportunities, an online Power BI course is one way to get started learning.
