What is the primary function of a QVD file in Qlik Sense?

The primary function of a QVD (QlikView Data) file in Qlik Sense is indeed to store data in a highly compressed format, which allows for faster loading and easy sharing across different applications. QVD files are specifically designed to optimize performance when handling large datasets by storing data in an efficient way that reduces the amount of space required.

This efficiency leads to quicker data retrieval times and enhances the overall user experience when accessing data in Qlik Sense applications. Furthermore, because of their standardization and ease of creation, QVDs can be reused across multiple applications, promoting consistency and simplifying the data architecture.

The other options do not accurately reflect the purpose of a QVD file. User interfaces for data entry are managed through different components in Qlik Sense, reports are generated through visualization tools rather than being a primary function of QVDs, and data linking is handled through associative data models and data load scripts rather than being a direct function of QVD files themselves.
