System design architecture style selection depends on your team size and DevOps maturity, guiding you from monoliths to modular monoliths or microservices. A modular monolith suits smaller teams, while microservices require higher DevOps maturity for scalable, maintainable software systems.

You need distributed system patterns like Saga, CQRS, and Event Sourcing when managing complex workflows and data consistency in distributed architectures. These patterns guide pattern implementation for robust, scalable software architectures handling intricate operations.

The best way to document software architecture decisions is by using Architecture Decision Records (ADRs) and the C4 model for visualization. These practices capture design rationale and communicate structural choices effectively across your engineering team.

You evaluate quality attributes during software architecture design using the ATAM method. This analysis helps assess performance, scalability, and maintainability, ensuring your selected architecture styles and patterns meet the necessary system requirements.

Domain-Driven Design (DDD) works seamlessly with Clean Architecture, Hexagonal, and Onion patterns to isolate business logic. Combining these architectural patterns ensures your core domain remains robust, maintainable, and independent of external infrastructure concerns.

The best way to decide between PostgreSQL and MongoDB is by evaluating your project's data structure needs. Technology stack guidance recommends relational databases for structured data and document databases for flexible schemas during system design.
