    Study Notes

    Power BI Content Types

    • Power BI supports reports, dashboards, and apps.
    • Reports are multi-page documents for publishing large datasets.
    • Dashboards are single-page visual summaries from reports.
    • Apps package Power BI content from various sources.

    Power BI Workspaces

    • A workspace is a private user area for developing content.
    • Workspaces can contain datasets, reports, dashboards, and Excel workbooks.
    • Users can create multiple workspaces.
    • Shared workspaces allow team collaboration.
    • Administrators control workspace creation and access.

    Power BI Security Model

    • Architecture: Two clusters (Web Front End - WFE & Back-End)
    • User authentication: Azure Active Directory.
    • WFE Role:
      • Initial connection and user authentication
      • Azure Traffic Manager (ATM) directs to nearest data center.
      • Retrieves user's subscription and security tokens from Azure Active Directory (AAD). -Locates the relevant Back-End cluster.
      • Sends requested resources to user's browser.
    • Back-End Role:
      • Handles all Power BI operations for authenticated users.
      • Data connections, visualizations, and data storage.
      • Data Storage: Azure Blob for imported data (e.g., Excel), Azure SQL Database for other data (e.g. tenant, workspaces).
      • Data Read Methods: Import (data copied to Power BI), DirectQuery (data referenced).
      • Modules: Gateway Role, Presentation Role, Data Role, Background Job Processing Role, Data Movement Role. Gateway & API Management are accessible via internet.
    • Data Access:
      • Imported data (e.g., from Excel) is read into an Analysis Services in-memory database and stored in Azure Blob encrypted.
      • DirectQuery data exists only while being processed (e.g., user access).
      • Data at rest is always encrypted.

    Power BI Dashboards in Mobile Apps

    • Dashboards summarize data with visuals for specific stories.
    • Dashboard design considers screen size (particularly for mobile use).
    • Scrolling is possible for large dashboards.
    • Dashboard customization includes tile moves, resizing, and added titles.
    • Mobile view arranges tiles vertically.
