@datascibykashi: If you’re learning Data Science or SQL, this is a must-know skill. Data modeling is how we design tables, relationships, and keys so data is: ✔ accurate ✔ scalable ✔ fast to query SQL Example (Core Idea): CREATE TABLE orders ( order_id INT PRIMARY KEY, customer_id INT, order_date DATE, FOREIGN KEY (customer_id) REFERENCES customers(customer_id) ); This shows: • Primary Key → unique identity • Foreign Key → table relationships • Normalized structure → clean analytics Good data models = Better joins Faster dashboards Reliable ML features 💡 This is used in real data engineering + analytics jobs, not just exams. 💬 Comment to Boost Engagement 👉 Comment “MODEL” if you want: • 1NF → 3NF explained • Star vs Snowflake schema • Real-world SQL case study #educatoraward #datascience #sql #datamodeling #dataanalytics
