• CTEs (Common Table Expressions) for readable queries
• Optimization: Reading execution plans, indexing
• Cloud SQL: Snowflake SQL, BigQuery, Azure Synapse, Fabric SQL - rapidly expanding with cloud migration

SQL mastery can increase your salary by 5 to 10% compared to profiles who only know the basics.

2. Python: The Data Analyst's Swiss Army Knife

Python has established itself as the reference language. Focus on:

• Pandas: Data manipulation and cleaning
• Polars: High-performance alternative to Pandas, increasingly adopted for large volumes
• NumPy: Numerical calculations
• Matplotlib / Seaborn: Data visualization
• Jupyter Notebooks: Interactive environment for reproducible analyses

5. Microsoft Fabric and dbt: Modern Data Stack Essentials
