When creating a new application to analyze sales data, which fields must be present in the QVD file?

The choice that highlights the essential fields for analyzing sales data is significant in defining key metrics and dimensions that enhance reporting capabilities. The fields present in the QVD file typically include attributes that allow users to perform comprehensive data analysis.

For effective sales analysis, the inclusion of the transaction date is critical as it enables time-based comparisons and trends. The country field provides geographical context, allowing for location-based insights or segmentation. The sales amount is a fundamental financial metric that indicates revenue generated and contributes to performance evaluations. Lastly, the product ID serves as a unique identifier for products, facilitating analysis related to sales performance on a per-product basis.

Together, these fields create a holistic view of sales data, making it easier for analysts to draw meaningful conclusions and develop actionable insights from their findings, thus underscoring the importance of this specific combination in the dataset.
