Mastering SQL Joins is essential for every data professional.
• Inner Join: Matching rows only
• Left/Right Inclusive: Keep all rows from one side
• Left/Right Exclusive: Keep non-matching rows
• Outer Inclusive: Combine all data
• Full Outer Exclusive: Return only non-matching rows

These joins turn raw tables into meaningful insights.
