For Beginners to start

Hi Nayan2013 

If I were teaching report development the way it's typically done from scratch, I'd begin with data transformation and preparation in Power Query (if data isn't in the proper shape yet or  there are rows and columns that aren't needed or don't exist at the source), followed by data modelling (building relationships), then creating visuals, and finally writing DAX measures. That sequence provides a solid foundation and is generally easier to follow when learning the basics.

That said, real-world report development is rarely that linear. In practice, you'll often find yourself moving back and forth between these areas. For example, building a visual might reveal that you need a new DAX measure, which then uncovers the need to adjust your data model or make additional transformations in Power Query. Developing Power BI reports is usually an iterative process rather than a strict step-by-step workflow.

Hi Nayan2013  As a beginner to the analytics platform you can start understanding about the Statistics concepts. Then from Power BI appliation, understand the Power BI ecosystem of Desktop, Service, Mobile. Get familiar with the interface having Report view, Data view, Model view. Learn how to connect to basic data sources like Excel, CSV files.

Importing and shaping data. Common transformations: remove columns, filter rows, change data types, merge and append queries. Understand the difference between Import and Direct Query.

Star schema and snowflake schema. Creating relationships between tables with cardinality, cross-filter direction. Fact tables and dimension tables.

Start with simple calculated columns and measures. Learn the functions of SUM, AVERAGE, COUNT, CALCULATE, FILTER. Understand row context and filter context. Then you can move on to Time intelligence functions.

Learn commonly used visuals like bar or column charts, line charts, cards, slicers, tables and matrix. Formatting and interactivity like drill-through, bookmarks, tooltips then start building a dashboard

Also you can participate in the monthly Data Challenges from Onyx Data, FP20 Analytics Challenges Group, etc (you can check for the updates in their LinkedIn page for more info) to showcase your learnings and building an insightful report.

A good learning order is

1. Power BI interface and basic report creation
2. Data import and Power Query (cleaning & transformation)
3. Data modeling (relationships, star schema, cardinality)
4. Visualizations and report design best practices
5. DAX fundamentals (measures, calculated columns, CALCULATE, FILTER)
6. Time intelligence functions (YTD, MTD, QTD, SAMEPERIODLASTYEAR)
7. Publishing reports and Power BI services
8. Row-Level Security (RLS) and data refresh
9. Performance optimization and best practices
10. Build end-to-end projects to apply everything you've learned
