What is Migration?

A controlled way to change your database structure over time, with the ability to undo changes

Why It Matters

Migrations let you evolve your database safely and keep track of all structural changes

Real-World Example

A migration that adds a 'phone_number' column to the users table

“Understanding terms like Migration matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
