Question #: 42
Topic #: 6

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:

1) install the related PHP libraries manually so the application will run;

2) use MongoDB, instead of MySQL, in the development environment.

According to the Twelve-Factor methodology, which changes should an Architect recommend?

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

BPersist code dependencies in the application's production database. Use the same type of database locally to ensure that the dependencies are accessible.

CRecursively determine code dependencies on application startup and maintain separate Git branches for the MongoDB- and MySQL- compatible versions of the application.

DExplicitly declare code dependencies in the application's source and use the same type of database in both development and production.

Option E: Install a crystal ball and just hope for the best. That's the developer's way, right?

Option B sounds like a disaster waiting to happen. Storing dependencies in the production database? That's just asking for trouble. I'll have to go with D on this one.

Haha, Option C is just crazy talk. Maintaining separate Git branches for different database versions? That's way too much work. I'll stick to something more straightforward.

I actually think Option A is the way to go. Environment variables are the way to go for managing dependencies, and keeping the same database type across environments is a best practice.
