🔄 3) General Workflow in Power BI
Power BI follows a structured workflow, enabling seamless data analysis and reporting.
a) 📥 Data Gathering
The first step is importing data from various sources. Power BI supports:
- Excel
- CSV
- SQL Server
- SharePoint
- Web APIs
- Google Analytics and many more
You can connect to live data sources or import static data depending on your business needs.
b) 🧹 Data Preparation
Once data is loaded, it often requires cleaning and shaping. This is done using Power Query Editor, where you can:
- Remove duplicates
- Transform columns
- Merge or append queries
- Filter unnecessary data
This step ensures the data is clean, structured, and ready for modeling.
c) 🔗 Data Modeling
In this phase, relationships are created between tables using primary keys, foreign keys, and joins. Users also create measures, calculated columns, and define data hierarchies using DAX (Data Analysis Expressions).
d) 📊 Reporting
Once the model is ready, users design interactive visual reports using a wide range of charts, graphs, maps, and KPI cards. You can add slicers, filters, drill-through pages, and bookmarks to make reports more dynamic.
e) ☁️ Publishing the Report to Power BI Service
After creating the report in Power BI Desktop, it is published to Power BI Service. This enables cloud access, version control, and collaboration.
f) 🧩 Creating Dashboard
Dashboards are created by pinning visualizations from multiple reports to a single page. These are often used by executives or managers to monitor KPIs at a glance.
g) 📤 Sharing the Reports & Dashboards
Finally, you can share reports or dashboards via:
- Direct share (email invite)
- App workspaces
- Embed in SharePoint or websites
- Export to PDF or PowerPoint
With proper permissions and access controls, you ensure data is securely shared with the right audience.
