What action can enhance the structure of imported data in Power BI?

• A. Exporting the data to another application
• B. Applying data types and validation rules
• C. Ignoring data inconsistencies
• D. Using pre-set templates exclusively

Answer: (B)

Enhancing the structure of imported data in Power BI can significantly improve the quality and usability of the analysis performed. Applying data types and validation rules is a fundamental step in this context. When you import data into Power BI, the software tries to automatically detect and assign data types to each column, such as numeric, text, date, etc. Properly defining these data types ensures that the data is interpreted correctly in visualizations and calculations. Furthermore, validation rules help maintain data integrity by enforcing certain constraints on the data. For instance, you may want to ensure that a particular column only contains valid dates or that numerical fields fall within a specific range. By applying these rules, you can prevent errors and ensure that the data model reflects accurate and meaningful insights. On the other hand, options such as exporting data to another application or using pre-set templates may not directly address the underlying structure of the data itself. Ignoring data inconsistencies can lead to erroneous analyses and misleading conclusions, making it crucial to correct those inconsistencies through careful structuring and validation. Thus, focusing on data types and validation enhances the reliability and effectiveness of your Power BI reports and dashboards.
