Today, I explored a mix of SQL and Power BI concepts. Let me break down what I learned:
๐น SQL Concepts
- AUTO INCREMENT โ Automatically generates unique IDs for new rows.
- ADD COLUMN โ Helps in adding new fields to an existing table without rewriting it.
- REMOVE ROWS & REMOVE DUPLICATES โ Essential for cleaning messy datasets.
๐น Power BI Concepts
- Data Modeling โ Building relationships between tables to analyze data effectively.
- Link Table โ Used to connect datasets and establish many-to-many relationships.
- DAX (Data Analysis Expressions) โ Learned how to use formulas, constants, and expressions for advanced calculations.
- Data Calculator Table โ Creating calculated tables for additional insights.
- RANK & DENSE RANK โ Functions that help order data and handle ties differently.
๐น 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.
๐ก Each day, I feel one step closer to becoming a professional Data Analyst.
Consistency and practice are making the concepts more natural ๐
๐ Follow my journey as I continue learning Data Analytics step by step!
