What is Rails Migration?
When you work with Rails Migrations, it’s important to embrace change. These migrations are a method that lets you adjust your database design in your Rails app in an organized way. They allow you to use Ruby code instead of SQL, which has its advantages.

Instead of dealing with SQL scripts directly, you define the database changes within a DSL (Domain-Specific Language). This code is independent of any specific database, so you can move your app to a new platform easily. You can make changes to SQL parts, inform your team, and then run these changes. Also, it’s important to keep track of the changes that need to be made on production machines the next time your app gets updated.

In simple terms, think of a migration as a new version of your database. Each migration modifies the database by adding or removing tables, columns, or data. Active Record manages this process and updates the db/schema.rb file to match the current structure of your database.

Why are Rails Migrations Important?
Rails Migrations are a useful tool in Ruby on Rails. They’re crucial for managing databases and developing applications. Here are some key features of Rails Migrations that make it easier to create strong and easy-to-manage applications:

Alter the Database Structure in a Controlled and Uniform Manner
With Migration Rails, you can change database elements like tables and columns while keeping it reversible if needed, ensuring data integrity and providing the ability to undo changes easily.

Database Independence
Since Migrations are coded in Ruby and not SQL, they are adaptable to any database supported by Active Record. This means you can easily switch your application from one database type to another if required.

Version Controlled
You can keep track of your application’s database changes by storing migrations in your source code repository. This helps you see all the modifications made to your database and revert to an earlier version if required.

Easy To Use
The Rails migration generator makes it easy to create and update new migrations. You can apply the pending migrations in your database using the command ‘rake db:migrate’.
