Today, I explored a mix of SQL and Power BI concepts. Let me break down what I learned:
πΉ 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.
πΉ 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.
πΉ 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.
π‘ Each day, I feel one step closer to becoming a professional Data Analyst.
Consistency and practice are making the concepts more natural π
