    (Raw Data → Model → Report → Dashboard)

    Let’s understand the complete lifecycle:

    Step 1: Raw Data

    • Data comes from Excel, database, cloud

    • Usually messy & unstructured

    Step 2: Data Transformation (Power Query)

    • Remove duplicates

    • Handle missing values

    • Change data types

    • Create new columns

    Step 3: Data Modeling

    • Create relationships between tables

    • Define primary & foreign keys

    • Create measures using DAX

    Good modeling = Better performance + accurate reports

    Step 4: Report Creation

    • Add charts, tables, KPIs

    • Apply filters & slicers

    • Make interactive visuals

    Step 5: Dashboard (Power BI Service)

    • Pin visuals from reports

    • Combine multiple reports

    • Share with management

  • Import vs DirectQuery

    Power BI offers two main data connection modes:

    Import Mode

    Data is copied into Power BI.

    Advantages

    • Fast performance

    • Full DAX support

    • Works offline

    Disadvantages

    • File size increases

    • Needs manual/auto refresh

    Best for:

    • Small to medium datasets

    • High-performance dashboards


    DirectQuery Mode

    Data stays in source database. Power BI sends live queries.

    Advantages

    • Real-time data

    • No large file size

    Disadvantages

    • Slower performance

    • Limited DAX features

    • Depends on database speed

    Best for:

    • Large datasets

    • Real-time reporting
