Which of the following is a major advantage of using
Power BI over traditional Excel charts for data visualization?Solution
One of the key advantages of Power BI over traditional Excel charts is its ability to integrate with real-time data sources and cloud services , enabling users to create live dashboards that update automatically as new data becomes available. This is especially useful in industries like finance and retail where decision-makers require up-to-the-minute information. Excel, on the other hand, is more static and does not support real-time data integrations natively, unless additional plugins or manual updates are performed. Why other options are wrong: a) Power BI allows for more complex data processing tasks : While Power BI is powerful, Excel also offers advanced features for data processing, such as Power Query and VBA, which can be just as capable for complex tasks. b) Power BI offers automated forecasting capabilities : Power BI does have forecasting features, but these are limited compared to specialized tools for forecasting like R or Python libraries. d) Power BI automatically cleans and preprocesses raw data : While Power BI has tools for data transformation, cleaning and preprocessing often require manual intervention, similar to Excel’s Power Query. e) Power BI allows for creating complex SQL queries directly within the tool : Although Power BI can connect to databases and run SQL queries, it is not primarily designed for writing and executing complex SQL queries, which is more of a feature of database management tools like SQL Server Management Studio.
