A deep understanding of how canvas apps and model-driven apps interface with automation is vital. This comprehension is even more pivotal because Microsoft Power Automate facilitates the creation of automated workflows between applications and data.
Canvas Apps and Automation
Canvas apps allow developers to design and build a business app from scratch, letting them employ an intuitive visual designing interface to layout the user interface. This eliminates the need to focus on creating the underlying functionality and logic, instead of focusing on the app’s appearance and user experience.
Automation in canvas apps aligns with these app-specific triggers or UI flows. For instance, Power Automate introduces UI flows, a robotic process automation (RPA) feature that allows automating manual business processes. UI flows can integrate with a canvas app to record and automate redundant user interface actions across DOS, Windows, and Web applications.
Consider a simple canvas app example that allows users to track their to-do tasks. An app-specific workflow could be designed to send a daily automated email recap of the day’s completed tasks. This requires using Power Automate to create a new scheduled flow attached to the canvas app, which activates at day-end, pulls completed tasks, and sends an email to the user.
Model-Driven Apps and Automation
Unlike canvas apps, which are designed from a blank canvas, model-driven apps in Power Apps allow developers to design an application using a robust application modeling framework that uses the data-first approach. The entire layout and design are based on the data model and business processes defined within Dynamics 365.
Business process flows in model-driven apps are a form of automation as they guide users through predetermined processes. They can be designed using Power Automate and ensure data consistency and adherence to processes. Also, model-driven apps can use other auto features like automated workflows and functions, business rules, and more.
As an example, consider a sales application that keeps track of potential opportunities. A business process automation flow could be designed for the sales process, beginning from a new lead’s entrance through qualification, development, proposal, and finally, to closing.
The below table summarizes the differences:
| – | Canvas Apps | Model-Driven Apps |
|---|---|---|
| User Interface | Fully customizable | Defined by components |
| Data Usage | Connects multiple sources | Structured around single source |
| Automation Support | App-specific Triggers and UI Flows | BPFs, automated workflows, and functions |
While both types of apps offer distinct automation interfaces, the method of implementing automation often depends on the specific needs of the app and the data it uses. The focus should always be on optimizing the business process, improving productivity, and creating a stellar user experience, which both canvas and model-driven apps support when integrated with automation in Power Automate.
Remember, canvas and model-driven apps, paired with Microsoft Power Automate, serve as a dynamic mechanism for transforming tedious manual tasks into efficient automated processes. As a prospective candidate for the PL-500 Microsoft Power Automate RPA Developer exam, understanding their functionality, use-cases, and interconnection is crucial for designing productive business solutions.
