Which development model does Power Apps Model-driven Apps follow?

Power Apps Model-driven Apps indeed follow a data-first approach, which is fundamentally built around Microsoft Dataverse. This approach emphasizes the importance of the underlying data model, which allows developers and business users to create applications that are deeply integrated with data along with comprehensive business logic and processes.

In this model, the design of the application is centered on the data structure rather than the code or visual elements. Microsoft Dataverse provides a robust data platform that includes standardized entities, relationships, and business rules, enabling users to create applications that can leverage these data-driven components effectively. This aligns with the core purpose of Model-driven Apps, which is to facilitate complex business solutions by utilizing relational data efficiently.

This approach also allows for a seamless experience when developing applications that need to adapt to changing data requirements, making it a dynamic and efficient way to deliver applications that meet user needs. Developers can focus on building relationships, business rules, and workflows that interact with the data stored in Dataverse, ensuring that the applications not only present data but also function based on interactions with that data in real-time.
