At Universal Containers (UC), a developer named Yuichiro wrote a PHP application that, in production, uses a MySQL database. Yuichiro is onboarding Mary, a new UC developer, who is setting up her development environment. Yuichiro asks Mary to:

AExplicitly declare code dependencies in the application's environment variables and use the same type of database in both development and production.

Option D makes the most sense to me. Declaring dependencies in the source code and using the same database in both environments aligns with the Twelve-Factor methodology.

Yes, I agree with Kallie. We should explicitly declare code dependencies in the application's source and use the same type of database in both development and production to follow best practices.

But shouldn't we use the same type of database in both development and production, as per the Twelve-Factor methodology?

Mary, I recommend you to install the related PHP libraries manually so the application will run.
