Box 1: business rules
You can create business rules and recommendations to apply logic and validations without writing code or creating plug-ins. Business rules provide a simple interface to implement and maintain fast-changing and commonly used rules.
Box 2: business process flows
Flows Power Automate includes several types of processes, each designed for a different purpose:
* Automated flows. Create a flow that performs one or more tasks automatically after it's triggered by an event.
* Button flows. Perform repetitive tasks simply by tapping a button on your mobile device.
* Scheduled flows. Create a flow that performs one or more tasks on a schedule such as once a day, on a specific date, or after a certain time.
* Business process flows. Ensure that people enter data consistently and follow the same steps every time they work in an app by creating a business process flow.
* Workflows and actions. Dynamics 365 customizers may be familiar with the classic Common Data Service processes, which are workflows and actions.
Box 3: Common Data Model
Model-driven app design is a component-focused approach to app development. Model-driven app design doesn't require code and the apps you make can be simple or very complex. Unlike canvas app development where the designer has complete control over app layout, with model-driven apps much of the layout is determined for you and largely designated by the components you add to the app.

Box 1: Flow Checker
The Flow checker feature will promote higher quality flows by ensuring you follow best practices. By running the checker, you will be able to get answers to questions like: which areas of my flow implementation pose a performance or reliability risk?
For each issue identified, the Flow checker points to specific occurrences within the flow where improvements may be required. And more importantly, you learn how to implement these improvements by following detailed guidance.
