By injecting the IConfiguration interface in the data access layer's constructor, the HomeController can simply call the DAL methods without directly managing the database connection details.

Implicit-based Dependency Injection in Scala provides a lightweight, type-safe alternative to traditional DI frameworks, simplifying dependency management without sacrificing compile-time verification.

"To overcome most issues we can use Dependency Injection (DI). Swapping in a new implementation becomes much easier as components don't rely on a single shared instance but on protocols that can be implemented in different ways. This promotes flexibility, easier testing, and adaptability as app requirements evolve."

Using AOP in Spring allows for cleaner code by separating cross-cutting concerns such as logging from the business logic, improving maintainability and readability.

A cyclic dependency occurs when two or more beans in Spring depend on each other, creating a cycle that can lead to initialization errors.
