Wrapping Up: Make Changes to Your Database

What we’ve learned?

Ecto’s migrations help us manage the structure of our database throughout the lifetime of our application. We have covered the main features of migrations in this chapter. We can also read through the migrations with the MusicDB codebase to see more real-life examples. This wraps up our tour of the main Ecto modules. Now that we have a solid understanding of the basics, we’re ready to look at some more advanced topics in Part II. Feel free to skip around and focus on the most interesting chapters to you. Each chapter in Part II stands on its own and can be read in any order.
