Study Notes

Data Sources in Canvas Apps

  • Canvas apps offer complete control over app appearance. They connect to data sources for functionality.
  • Data sources are accessed through connectors in Power Platform.
  • Many data sources are available, including cloud-based storage services (OneDrive for Business, SharePoint), cloud-based databases (Microsoft Dataverse), and applications from local servers and the cloud.
  • Connectors are categorized as standard (accessing Microsoft cloud services, basic internet, and social media) or premium (accessing higher-end commercial apps like SQL Server, Dynamics 365, and Azure services).
  • Some sources are for storing data generated by the app (like SharePoint, Microsoft Dataverse), while others are sources of data for presentation (e.g., Excel spreadsheet from OneDrive for Business).

Data Source Types

  • Tables (spreadsheets, SharePoint lists, SQL tables) are common data used by apps.
  • Apps can read, modify, and add data to tables.
  • Non-tabular data sources like calendars and email messages are also accessible.

Connecting to Data Sources

  • Connecting to a data source is the first step in app creation.
  • Three methods to create a canvas app:
    • Start with a blank app: The developer navigates to the Data pane, selects Add data, and chooses a data source. Different data sources offer different interfaces for accessing their data.
    • Start with a data source: The developer chooses a pre-selected data source (e.g., Excel, SharePoint). An existing connection might already exist, otherwise a new connection is established.
      • Power Apps will analyze the data source to help create an initial app structure (e.g. a catalog app). The app can subsequently be edited.
    • Start from a template: Using a ready-made template that has a structure and potentially sample data. Developers can adapt templates for their needs.
