Data sources, connections, and gateways

In Power Apps, most canvas apps use external information that is stored in Data Sources. A common example is a table in an Excel file that is stored in OneDrive for Business or SharePoint. Apps access these data sources by using connections. Some connections allow Power Apps to read and write stored data. In Power Apps, you can add many data sources to your apps through built-in or custom connectors. Some of the most popular data sources are shown in the following figure.

Microsoft Dataverse

An important data source option to explore further is the Dataverse. Dataverse lets you store and manage data that‘s used by business applications. Data within Dataverse is stored within a set of tables. A table is a set of records that are used to store data, similar to how a table stores data within a database. Dataverse includes a base set of standard tables that cover typical scenarios, but you can also create custom tables that are specific to your organization and then populate them with data by using Power Query. App makers can then use Power Apps to build rich applications by using this data.
