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.
