Introduction to Power BI in 10 Minutes

Overview

• Power BI is a tool to uncover stories and make decisions based on data.
• We'll cover:
  • Importing data
  • Building a data model
  • Adding visuals and filtering
  • Sharing reports and dashboards

Getting Power BI

• Open Microsoft Store and search "Power BI."
• Three options available:
  • Power BI: View and interact with reports.
  • Power BI Desktop: Full functionality to model data and build reports (used in this guide).
  • Report Builder: Similar to desktop but less feature-rich.

Initial Setup

• After launching Power BI Desktop:
  • Splash screen offers data access and learning resources.
  • Options to disable splash screen.
• Main report view:
  • Import data via "Get Data" on "Home" tab.
  • Various data sources available.

Importing and Transforming Data

• Example using Excel workbook with tables: "Customers" and "Orders."
• Options upon import:
  • Load Data: Import as is.
  • Transform Data: Modify data before importing (useful if original data is uneditable).
• Power Query Editor allows data modification:
  • Replace inconsistent values (e.g., "US" to "United States").
  • Remove unnecessary columns (e.g., "Rush Shipments").
  • Changes don't affect original data, only imported copy.

Building a Data Model

• Use "Model view" to understand relationships between tables.
• Automatic detection of relationships (e.g., Customer ID linking "Customers" and "Orders")
• Manual relationship establishment by dragging fields between tables.

Creating Reports

• Reports are collections of visualizations.
• Choose visualizations like line charts, bar charts, tables, etc.
  • Line Chart: Cookies shipped over time.
  • Card: Total revenue display.
  • Table: List of all customers.
• Interactive elements allow filtering (e.g., selecting a customer filters data across visuals).

Finalizing and Sharing Reports

• Add additional pages for varied data views.
• Share with team for feedback:
  • Use "Publish" option; save and choose a workspace.
  • View report on Power BI web service.
  • Share via file menu options:
    • Embed in SharePoint, websites, generate QR codes.
    • Export as PowerPoint, PDF.
    • Share via email, link, or Microsoft Teams.
