Canvas apps are an integral part of the Microsoft Power Platform. They allow users to easily design, build, and share custom business apps without requiring traditional coding knowledge. The canvas app model provides a highly flexible layout that allows users to freely arrange elements on a canvas. In this article, we will discuss use cases for and capabilities of canvas apps.
I. Use Cases for Canvas Apps
- CRM Applications: Canvas apps built on top of Common Data Service (CDS) can leverage the power of the data model and business rules within the HRS (Human Resource System) or CRM (Customer Relationship Management) to automate and optimize business processes, providing a scalable and secure enterprise infrastructure.
- Employee Management: Canvas apps can also be used as a task management system. Tasks can be assigned to employees and updates can be tracked without relying on any other platform. Employees can view their tasks within the app and mark them as completed once done.
- Custom Surveys and Feedback: A canvas app can be built to collect customer feedback or conduct surveys. The app’s interface can be designed to align with the survey’s requirements, and the data collected can be stored and analyzed for future reference.
II. Capabilities of Canvas Apps
- Integration with Data Sources: Canvas apps can connect with different data sources, both within and outside the Microsoft ecosystem. This includes SharePoint, Excel, SQL Server, and many others. This makes it versatile in the choice of data and allows the use of the data already existing in these sources.
- User Interface Customization: Unlike the model-driven apps, canvas apps’ user interface is not determined by the underlying data structure. This gives the developer full control over how they want the app to look and function.
- Sharing Capability: Once you create a canvas app, you can easily share it with others within your organisation. It can be shared either individually or as part of a solution.
- Enterprise-grade Security: Canvas apps leverage the same enterprise-level security as the rest of the Power Platform. It respects the data policies and privacy requirements established by the organization.
Table: Canvas Apps vs Model-Driven Apps
| Canvas Apps | Model-Driven Apps | |
|---|---|---|
| User Interface | Fully customizable | Defined by the data structure and business process |
| Data Sources | Can connect to multiple data sources | Mostly uses Common Data Service |
| Scalability | Not typically meant for complex scenarios | Built to handle more complex requirements |
| Setup | Design-first approach | Data-first approach |
In conclusion, canvas apps provide a robust platform for users to build bespoke applications tailored to their specific business needs. Their capabilities can be leveraged to design apps for simple task management purposes to complex CRM purposes. However, to fully utilize canvas apps’ capabilities, potential users should have a good comprehension of their business requirements and the tools at their disposal. Understanding the strengths and limitations of these apps can lead to more efficient development and ultimately, a more effective business solution. As you prepare for the PL-900 Microsoft Power Platform Fundamentals exam, a thorough understanding of canvas apps is key to mastering the Microsoft Power Platform.
