What does "model-driven app" imply in the context of Power Apps?

The term "model-driven app" in Power Apps indicates that the app's design and architecture are primarily centered around data and business processes. This approach leverages the Common Data Service (now known as Microsoft Dataverse) to define the data structure, relationships, and business logic, thus ensuring that applications are built upon a solid data foundation.

Model-driven apps allow users to create sophisticated layouts that can automatically adjust to changes in data within the system. They are designed to optimize complex data relationships and workflows, making them suitable for enterprise-level solutions requiring robust data interactions and user experiences guided by underlying business processes.

This contrasts with other choices: the notion of requiring coding expertise does not inherently apply to model-driven apps since they can be created using low-code or no-code techniques. Similarly, describing them as simple mobile apps misrepresents the functionality and sophistication they can offer. Lastly, while custom-built applications can certainly be user-focused, model-driven apps specifically emphasize the importance of data and business processes above customization.
