What are database migrations in MVC applications?

Database migrations are a way to manage changes to your application's database schema over time. They allow you to version control your database changes, making it easier to apply, roll back, or share changes with your team.

How do I create a migration in an MVC app?

You can create a migration using the command line. For example, in ASP.NET MVC, you would use the command Add-Migration MigrationName in the Package Manager Console.

Can I roll back a migration if something goes wrong?

Yes, you can roll back a migration using the command Update-Database -TargetMigration PreviousMigrationName. This will revert your database to the state before the specified migration.

What happens if I forget to update the database after creating a migration?

If you forget to update the database, the changes defined in your migration won't be applied, and your database schema will remain unchanged.
