Power Apps is a suite of Microsoft products that enable both developers and non-technical users to build custom applications to fulfill various business needs. It is a low-code platform that allows users to quickly build custom business apps that connect to data stored either in the underlying data platform (Microsoft Dataverse) or in various online and on-premises data sources (such as SharePoint, Microsoft 365, Dynamics 365, SQL Server, and so on). Power Apps provides a rapid development environment to build custom apps for your business needs, and it democratizes the business-app-building experience by enabling users to create feature-rich, custom business apps without writing code.

Power Apps provides a suite of apps, services, and connectors, as well as a data platform, that allows users to create three types of apps: canvas, model-driven, and portal. Canvas apps are designed for building custom user interfaces that connect to a wide variety of data sources, while model-driven apps are designed for building complex business applications that are built on top of a data model, and portal apps are designed for building external-facing websites that allow users to interact with data stored in the underlying data platform.

Apps built using Power Apps provide rich business logic and workflow capabilities to transform manual business operations into digital, automated processes. They have a responsive design and can run seamlessly in a browser and on mobile devices (phone or tablet). Power Apps 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.

In summary, Power Apps is a low-code platform that allows users to quickly build custom business apps that connect to data stored in various online and on-premises data sources. It provides a rapid development environment to build custom apps for your business needs, and democratizes the business-app-building experience by enabling users to create feature-rich, custom business apps without writing code.
