What is the difference between Model driven app and canvas app?

Canvas Apps and Model-Driven Apps: These are two types of apps that can be built with Microsoft’s Power Apps platform, which allows people to create custom apps with little or no code.

Data-First vs UI-First Approach: Model-Driven Apps start with the data model and processes in the Common Data Service, while Canvas Apps start with the user interface and design. The platform controls most of the UI for Model-Driven Apps, but Canvas Apps give more flexibility and customization.

Different Use Cases and Goals: Model-Driven Apps are best for complex business logic, built-in components, and tight security. Canvas Apps are best for simple, task-based apps, flexible data sources, and custom UI/UX. Both types of apps can be combined to create a hybrid solution.
