save this + follow for part 3 to see the step-by-step of how to fix each of these in SQL 😉 Comment “data” for my free 5-day data career kickstart course to learn the basics of data careers, SQL, and portfolio building 🥰 Your data can look clean on the surface and still be a disaster underneath.💀 In part 1, I used @claudeai Code to build a dirty dataset AND a full answer key from scratch. Let’s explore that dataset and see what needs to be cleaned. Here’s what we found from the first look: ↳ duplicate order IDs hiding that would cause you to overcount in every aggregation ↳ inconsistent category values such as “Books” uppercase, lowercase, and spelled wrong, all being treated as separate categories ↳ columns that looked clean but were actually full of empty strings instead of nulls, meaning a basic null check would miss them entirely The last one is the sneaky one: Somewhere upstream in the ETL pipeline, nulls got coded as empty strings. You HAVE to know to look for it. Exploring dirty data before you touch it is the step most people skip. You can’t clean what you haven’t looked at 💀

nobody talks about SQL but it is one of the most requested skills in every data, backend, and analytics job posting right now. if you can write a clean query you are already ahead of half the applicants. save this and actually start this week because this one skill alone has landed people six figure jobs. #sql #datascience #machinelearning #ai #cs

Fundamentals Every Data Analyst Must Master!📊 SQL is one of the most important skills for anyone working with data🚀 Before jumping into advanced queries, it's crucial to build a strong foundation - because every dashboard, report, and analysis starts with structured data. Here are key SQL concepts every beginner should understand:⤵️ ✅Databases & Tables - how data is stored in rows and columns ✅Core Commands - CREATE, INSERT, SELECT, UPDATE, DELETE ✅Filtering Data - using WHERE, IN, BETWEEN, and LIKE ✅Sorting & Grouping - ORDER BY, GROUP BY, and HAVING ✅Handling Missing Values - working with NULL, IS NULL, IS NOT NULL ✅Data Integrity Rules - constraints like PRIMARY KEY and FOREIGN KEY ✅Combining Results - UNION, INTERSECT, EXCEPT SQL isn't just a tool - it's the language of structured data. If you're learning data analytics, mastering these fundamentals will take you very far.
