Question 1 of 30
In a retail company utilizing Power BI, the management team wants to analyze sales performance across different regions and product categories. They have data from multiple sources, including Excel spreadsheets, SQL databases, and cloud services. The team is particularly interested in understanding how to effectively integrate these diverse data sources into a cohesive Power BI report that provides actionable insights. Which approach should they prioritize to ensure a seamless data integration process while maintaining data integrity and performance?
Utilize Power Query to connect to each data source, transform the data as needed, and load it into the Power BI data model, ensuring that data types are consistent across sources.
Manually copy and paste data from each source into Power BI to avoid any potential connection issues.
Use only the SQL database as the primary data source and ignore the other sources to simplify the report creation process.
Create separate reports for each data source and then combine them in Power BI, which may lead to inconsistencies in data representation.
