πŸš€ Day 39 of My Data Analytics Journey !

 Today, I explored a mix of SQL and Power BI concepts. Let me break down what I learned:

πŸ”Ή SQL Concepts

  • AUTO INCREMENT β†’ Automatically generates unique IDs for new rows.
  • ADD COLUMN β†’ Helps in adding new fields to an existing table without rewriting it.
  • REMOVE ROWS & REMOVE DUPLICATES β†’ Essential for cleaning messy datasets.

πŸ”Ή Power BI Concepts

  • Data Modeling β†’ Building relationships between tables to analyze data effectively.
  • Link Table β†’ Used to connect datasets and establish many-to-many relationships.
  • DAX (Data Analysis Expressions) β†’ Learned how to use formulas, constants, and expressions for advanced calculations.
  • Data Calculator Table β†’ Creating calculated tables for additional insights.
  • RANK & DENSE RANK β†’ Functions that help order data and handle ties differently.

πŸ”Ή Practice Dataset

I also worked with a Restaurants dataset to apply these concepts practically. It really helped me see how data cleaning, modeling, and ranking functions come together in real-world scenarios.

πŸ’‘ Each day, I feel one step closer to becoming a professional Data Analyst.
Consistency and practice are making the concepts more natural πŸš€
