What core feature distinguishes model-driven apps in Power Apps?

Model-driven apps in Power Apps are distinguished by their data-driven design, which is fundamentally based on the Common Data Service (now known as Microsoft Dataverse). This means that model-driven apps are built around the data model and the relationships between data entities. The focus is on the data structure and its interactions, allowing developers to create applications that automatically generate user interfaces based on the underlying data schema.

This data-centric approach enables the rapid creation of complex applications without requiring extensive customization or coding. Users can design the application through a graphical interface that seamlessly integrates the data model, automating many aspects of the user experience based on the data provided. This is in contrast to canvas apps, which are more reliant on custom visual design and component placement.

Other options like dependency on SharePoint, simple UI elements, and integration with third-party apps do not capture the essence of model-driven apps. Python features do not necessarily relate to having a data-driven design, as model-driven apps can utilize various data sources beyond just SharePoint. Furthermore, the integration capabilities of model-driven apps are not limited to third-party applications, but are deeply tied to the organizational data managed within Dataverse.
