What is the purpose of a site map in model-driven apps?

The purpose of a site map in model-driven apps is to navigate between various components of the app. A site map serves as the navigation structure, essentially functioning as a map that provides users with a clear overview of how to move throughout the application. It allows users to access different areas of the app, such as entities, dashboards, and other components, facilitating easy navigation.

This navigation structure is crucial in model-driven apps because it helps users find the information and functionality they need quickly and efficiently. A well-designed site map enhances user experience and productivity, making it an essential aspect of the app’s design.

While the other choices touch on important features within the app, they do not directly relate to the primary function of a site map. For example, the data structure pertains to how the app's data is organized, dashboard layout involves visual presentation, and security roles focus on user permissions—none of which reflect the navigational aspect that the site map provides.
