๐ Data Analytics Essentials โ Skills Every Analyst Must Master
If you want to grow faster as a Data Analyst, itโs not just about tools.
You need the right mix of technical + business skills.
Hereโs a quick breakdown ๐
๐ง Technical Skills
1๏ธโฃ SQL
โข Joins, GROUP BY, Window Functions
โข Handling NULLs & duplicates
๐ก Example: Use LEFT JOIN to identify churn vs non-churn users.
2๏ธโฃ Excel
โข Pivot Tables, Lookups, IF logic
โข Fast data cleaning
๐ก Example: Summarize 50K rows instantly using pivots.
3๏ธโฃ Power BI / Tableau
โข Data modeling, measures, filters
โข Build dashboards that answer one clear question.
๐ Example: Track sales drop by region & month.
4๏ธโฃ Python
โข pandas for data cleaning
โข matplotlib / seaborn for quick visuals
๐ก Example: Cohort-wise revenue analysis.
5๏ธโฃ Statistics Basics
โข Mean vs Median, Variance, Correlation
โ ๏ธ Example: Median often explains salary distribution better than average.
โธป
๐ค Soft Skills (Equally Important)
1๏ธโฃ Business Thinking โ Always ask why before how.
2๏ธโฃ Communication โ Explain insights in simple terms.
3๏ธโฃ Problem Framing โ Convert vague questions into clear metrics.
4๏ธโฃ Attention to Detail โ Small data errors break trust.
5๏ธโฃ Stakeholder Management โ Listen first, challenge with data.
โธป
๐ Lesson:
Tools alone wonโt make you a great analyst.
The real edge comes from combining technical skills with business thinking.
๐ฅ Pick one skill from this list and improve it.

๐ Thinking of Hosting a Live SQL Interview Masterclass
Iโm considering conducting a live SQL interview masterclass where weโll solve real interview questions and learn the thinking process behind them.
Topics would include:
โข Conditional aggregation questions
โข Ranking & window function problems
โข Real interview questions from companies
โข Common SQL interview traps
It will be a small live session (max 50 people) so we can keep it interactive.

๐ Essential SQL Commands Every Data Professional Should Know
Whether youโre preparing for SQL interviews or working with databases daily, these commands form the backbone of SQL.
Hereโs a quick refresher ๐
๐น SELECT โ Retrieve data from a table
๐น INSERT โ Add new records into a table
๐น UPDATE โ Modify existing data
๐น DELETE โ Remove specific records
๐ฆ Database Structure
๐น CREATE โ Create new database objects (tables, databases)
๐น ALTER โ Modify the structure of an existing object
๐น DROP โ Delete an entire table or database
๐ Filtering & Analysis
๐น WHERE โ Filter records based on conditions
๐น GROUP BY โ Group rows with similar values
๐น HAVING โ Filter aggregated results
๐ Working with Multiple Tables
๐น JOIN โ Combine data from multiple tables
โก Performance
๐น INDEX โ Speeds up data retrieval in large tables
๐ Tip:
Mastering these fundamentals makes solving complex SQL problems much easier.

๐ Common SQL Window Functions You Should Know
Window functions = next-level SQL ๐
They help you analyze data without losing rows.
๐ข ROW_NUMBER()
Gives a unique number to each row
๐ Perfect for deduplication & ordering
๐ RANK()
Assigns rank with gaps
๐ If 2 people tie, next rank is skipped (1, 2, 2, 4)
๐ฅ DENSE_RANK()
Assigns rank without gaps
๐ No skipping (1, 2, 2, 3)
๐ SUM() OVER()
Calculates running totals
๐ Great for cumulative sales, revenue trends
โฎ๏ธโญ๏ธ LAG() / LEAD()
Compare with previous/next row
๐ Useful for time-based analysis, growth tracking
โก Why it matters?
Because real-world data problems need row-level + aggregated insights together
