Re-explain

Flyway supports three types of migrations:

Versioned Migrations: Applied exactly once, have version numbers
- Example: V1__Create_user_table.sql
Repeatable Migrations: Applied whenever their checksum changes
- Example: R__Update_user_view.sql
Undo Migrations: Used to reverse versioned migrations
- Example: U1__Undo_Create_user_table.sql
