# Architectural Decision Record for Payment Boundary
|
|
|
|
## Context
|
|
In order to ensure the integrity and separation of concerns within the payment processing system, we need to define firm boundaries between various components: Controller, Service, Repository, Domain, and Integration. This helps in minimizing unintended dependencies that may arise during development.
|
|
|
|
## Decision
|
|
The payment boundary will be strictly defined such that:
|
|
- Controllers interact only with Services.
|
|
- Services interact only with Repositories and Domains (no direct interaction between Services and Controllers).
|
|
- Repositories handle data access and business logic is encapsulated within Services.
|
|
- Integration with external systems is managed separately and will not cross into the Service layer.
|
|
|
|
## Alternatives
|
|
1. Allow Services to directly interact with Repositories for data retrieval.
|
|
**Consequences:** Increases coupling and can lead to issues with data integrity and business logic being bypassed.
|
|
2. Utilize an Event-Driven Architecture for communications between Services and Integrations.
|
|
**Consequences:** Increased complexity and potential performance hits.
|
|
|
|
## Consequences
|
|
By setting these boundaries, we are ensuring that changes in one component do not inadvertently affect others, thus maintaining a clean architecture that adheres to SOLID principles. Scalability and maintainability of the system are expected to improve as team members can work more independently without overlapping concerns. |
