What is PowerApps?
PowerApps is a suite of apps, services, connectors and data platform that provides a rapid application development environment to build custom apps for your business needs. Using PowerApps, you can quickly build custom business apps that connect to your business data stored either in the underlying data platform (Common Data Service) or in various online and on-premises data sources (SharePoint, Excel, Office 365, Dynamics 365, SQL Server, and so on).
Apps built using PowerApps provide rich business logic and workflow capabilities to transform your manual business processes to digital, automated processes. Further, apps built using PowerApps have a responsive design, and can run seamlessly in browser or on mobile devices (phone or tablet). PowerApps “democratizes” the custom business app building experience by enabling users to build feature-rich, custom business apps without writing code.
PowerApps also provides an extensible platform that lets pro developers programmatically interact with data and metadata, apply business logic, create custom connectors, and integrate with external data.
App for Makers/Creators
Using PowerApps, you can create two types of apps: canvas and model-driven. PowerApps is a high-productivity development platform for business apps, and it has three major components:
• Canvas apps start with your user experience, crafting a highly tailored interface with the power of a blank canvas and connecting it to your choice of 200 data sources. You can build canvas apps for web, mobile, and tablet applications.
• Model-driven apps start with your data model – building up from the shape of your core business data and processes in the Common Data Service to model forms, views, and other components. Model-driven apps automatically generate great UI that is responsive across devices.
• Common Data Service is the data platform that comes with PowerApps and allows you to store and model business data. It’s the platform on which Dynamics 365 applications are built; if you’re a Dynamics customer, your data is already in the Common Data Service.
