5. Collaboration and Sharing
Power BI Service: The cloud component where reports can be published, shared, and accessed by others within or outside the organization using Power BI Pro or Premium licenses.
Workspaces: Collaborative environments within Power BI Service where teams can work on datasets, reports, and dashboards together.
Apps: Package and distribute dashboards and reports in a controlled manner to specific recipients.
6. Security
Row-Level Security (RLS): Enables control over who can see what data, based on user roles or data attributes.
Azure Active Directory Integration: For managing user access and authentication.
7. AI Capabilities
AI Insights: Includes features like Quick Insights for automatic data pattern discovery, Key Influencers to understand factors affecting metrics, and Q&A for natural language queries against your data.
8. Mobile BI
Mobile Apps: Available for iOS, Android, and Windows, allowing users to consume, annotate, and interact with BI content on mobile devices.
9. Integration
Microsoft Ecosystem: Integrates seamlessly with other Microsoft tools like Excel, SharePoint, Teams, enhancing productivity and data flow.
Power Automate: For automating workflows that involve Power BI data.
10. Embedded Analytics
Power BI Embedded: Allows developers to integrate Power BI visuals and reports into custom applications without users needing a Power BI license.
11. Usage Tips
Start with Data: Ensure your data is clean and well-organized before visualization. Power Query can help with this.
Learn DAX: Even basic DAX knowledge can significantly enhance your reports by allowing custom calculations.
Use Templates: Leverage templates for common report types to speed up report creation.
Interactive Design: Design for interactivity; users often need to explore data beyond static views.
Performance: Be mindful of performance, especially with large datasets. Optimize by using appropriate data connections and avoiding unnecessary complexity in models.
12. Licensing
Power BI Free: For individual use with limited features.
Power BI Pro: Required for sharing and collaborating on content.
Power BI Premium: Offers dedicated cloud computing resources, capacity-based licensing, and features like paginated reports.
