They are the ideal platform to develop enterprise grade applications with efficient workflows and rich business logic, enabling businesses to shift their manual processes to more automated solutions, enabling digital transformation at its peak.
There are two methods to build a PowerApps application, you can opt for a Canvas App or a Model Driven App. What are the differences between the two?
Let’s find out by starting with the fundamentals like…
What is a Canvas App?
Canvas apps are true to their name and works on a design-first approach. PowerApps platform provides the user with a blank canvas, which is pretty much an empty screen. It comes with a drag and drop builder that allows users to move around different elements onto the canvas.
The elements can be multimedia elements, data tables, form charts and much more. This approach allows developers to create their apps from scratch, tailored to their workflow and project requirements.
Hence, as you can tell, Canvas applications are most suitable for designing custom interfaces and ideal for applications that focus on creating immersive user experiences.
Benefits of Canvas Apps
- Flexibility & Creativity: Canvas Apps provides a highly flexible & creative environment, allowing users to design their app interface from scratch with control over the minutest detail.
- Engaging User Interface: Drag-and-drop interface and customizable controls are the perfect ingredients for creating a visually engaging and appealing, user-interfaces.
- Integration with External Data: Users can easily integrate external data sources like datasets, SharePoint and APIs for enhancing the app’s functionalities & connectivity.
- Responsive Design: Canvas apps follow a design first approach, hence providing more control over the app’s responsiveness, ensuring a seamless user experience across all devices.
Limitations of Canvas Apps
- Complex for Non-Developers: Building complex business logic can be challenging for non-developers since it requires a deeper understanding of formulas and expressions.
- Maintenance Challenges: Maintaining updates & changes to the app interfaces can be time consuming, especially for large-scale applications.
What is Model-Driven App?
Model Driven Apps take a different approach then Canvas Apps in Power Platform. Where Canvas Apps are more UI-driven, Model-Driven apps are more ‘Data-Driven’ and focus more on the data model for their starting point. This data model can be fetched from an existing Microsoft Dynamics 365 or the Common Data Services platform, or be built from scratch.
They follow the philosophy of building towards a defined product or project in mind. Hence, the resulting app is more driven by the data rather than the user creating it. This approach is generally better suitable for apps that have standardized processes, consistent user experience, data-driven requirements and more such use cases.
Hence, it is certain that Model-Driven Apps are a better choice for enterprise grade applications that focus more on rapid development and secure applications with complex data handling requirements.
Benefits of Model-Driven Apps
- Rapid Development: Model-driven apps don’t need much ideation or conceptualization to work with. There are pre-built components and data models that guide the development process. This enables quicker development cycles, especially for apps with standardized data structures.
- Built-in Security Model: Model-driven apps come with a built-in security model based on MS Dataverse. This simplifies authentication and authorization processes and permissions handling requirements.
- Unified User Experience: Users get a uniformed user experience of a consistent interface due to implementation of a standardized layout. This promotes familiarity and hence improves the ease of use.
- Scalability: Model-Driven Applications are well-suited for enterprise app requirements since it is a scalable framework that can accommodate complex business processes and data requirements.
Limitations of Model-Driven Apps
- Limited UI Customization: Model driven power apps are far less customizable than Canvas Applications, limiting its ability to create unique and specialized designs.
- Learning Curve: Using the base level of model-driven apps is pretty straightforward, however, utilizing some of the advance features, that too with limited technical knowledge, can come with a steeper learning curve.
