Which two main functions does Power BI serve?

Power BI serves multiple functions in the realm of data analysis, but focusing on the two main functions of transforming and presenting data highlights its core capabilities. Transforming data involves cleaning, shaping, and organizing the data into a useful format that can be analyzed. Power BI provides powerful tools for data transformation, enabling users to manipulate their datasets to derive meaningful insights.

Once the data is transformed, Power BI excels in presenting that data through a variety of visualizations. It allows users to create interactive dashboards and reports that effectively summarize and communicate data trends, patterns, and key insights. This dual function of transforming and presenting data is vital for organizations looking to make informed decisions based on their data analytics.

While other choices touch on aspects that Power BI can perform, they do not encapsulate its primary role as effectively as transforming and presenting data. Collecting data, storing it, and ensuring data security are usually handled in conjunction with other data storage solutions and processes, rather than being primary functions of Power BI itself. Visualizing and summarizing data, while also important, is encompassed within the broader categories of transformation and presentation, making them slightly less comprehensive as descriptions of Power BI's main functions.
