What is the difference between Sequelize transactions and migrations?

Sequelize transactions are used to manage a series of database operations that should either all succeed or all fail, ensuring data integrity. Migrations, on the other hand, are used to modify the database schema over time, allowing you to version control your database changes.

Can you give me an example of when to use a transaction?

Sure! You would use a transaction when you need to perform multiple related operations, like transferring money between two accounts. If one operation fails, you can roll back the entire transaction to maintain consistency.

And what about migrations? When should I use them?

Migrations are useful when you need to update your database schema, like adding a new column or changing a data type. They help keep your database structure in sync with your application code.

Can I use transactions and migrations together?

Yes, you can! It's common to use transactions within migrations to ensure that schema changes are applied safely and can be rolled back if something goes wrong.
