What is Schema?

A blueprint that defines the structure of your data, including fields and their types

Why It Matters

Schemas ensure data consistency and help catch errors before they cause problems

A user schema might specify that email is required and must be a valid email format

An organised collection of data that your application can store, retrieve, and update

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

Checking that data meets requirements before processing it
