Day 14 of my 30-Day Data Analyst Journey!

Today, I worked with the powerful ALTER TABLE command in PostgreSQL. I learned how to:
✅ Rename a table
✅ Modify a column's data type
✅ Add constraints
✅ Add new columns to existing tables

These are essential steps when cleaning or updating real-world datasets.
