Capabilities of Power Apps¶

Overview¶

This domain covers Power Apps types, building applications, and integration capabilities. It represents 25-30% of the exam and focuses on understanding how to create custom business applications with low-code/no-code development.

Key Topics¶

Power Apps Types¶

• Canvas apps (pixel-perfect, flexible design)
• Model-driven apps (data-centric, form-based)
• Power Apps portals (external-facing websites)
• Differences and appropriate use cases for each type

Building Power Apps¶

• Creating canvas apps from templates
• Creating canvas apps from data sources
• Creating canvas apps from blank
• Creating model-driven apps from Dataverse
• Sharing and publishing applications
• App versioning and updates

Power Apps Integration¶

• Connecting to data sources (Dataverse, SharePoint, SQL, etc.)
• Using Power Apps with other Power Platform components
• Common connectors (Office 365, SharePoint, OneDrive)
• Custom connectors for proprietary systems
• Power Apps in Microsoft Teams
• Offline capabilities for mobile apps

Services Reference¶

Core Components¶

• Power Apps Studio (canvas app designer)
• Model-driven app designer
• Power Apps Mobile (iOS and Android)
• Power Apps portals
• Dataverse (underlying data platform)

Data Sources and Connectors¶

• Microsoft Dataverse
• SharePoint
• SQL Server and Azure SQL
• Excel and OneDrive
• Dynamics 365
• 350+ standard connectors
• Custom connectors

Best Practices¶

Canvas App Design¶

• Design for the target device (phone, tablet, desktop)
• Use consistent navigation patterns
• Implement responsive design principles
• Follow accessibility guidelines
• Keep formulas simple and maintainable
• Use components for reusability

Model-Driven App Design¶

• Start with Dataverse tables and relationships
• Use business process flows for guided experiences
• Configure forms for optimal user experience
• Create views for different user roles
• Implement business rules for validation
• Use security roles for access control

Data Integration¶

• Choose the right connector for data source
• Implement data validation
• Handle errors gracefully
• Use collections for performance
• Cache data when appropriate
• Implement proper authentication

Performance Optimization¶

• Minimize data calls in app startup
• Use delegation for large datasets
• Optimize gallery and collection usage
• Reduce number of controls on screens
• Use concurrent function for parallel calls
• Monitor app performance and errors

Common Scenarios¶
