## About

# Software Architecture

Reference companion for architecture reviews, system design sessions, and architectural
decision-making. Each topic lives in its own reference file.

## Reference Files

| File | Contents |
|------|----------|
| `references/fundamentals.md` | Architecture definition, architect role, architectural requirements, decisions, constraints, documentation (ADR, Architecture Haiku) |
| `references/architectural-styles-monolithic.md` | Layered, Pipeline, Microkernel — topology, trade-offs, when to use |
| `references/architectural-styles-distributed.md` | Microservices, Event-Driven Architecture (EDA), SOA — topology, principles, trade-offs |
| `references/architectural-patterns.md` | Hexagonal (Ports & Adapters), CQRS, Event Sourcing, MVC |
| `references/enterprise-patterns.md` | Domain logic patterns (Transaction Script, Domain Model), data source patterns (Active Record, Data Mapper), integration patterns (File Transfer, Shared DB, RPC, Messaging) |
| `references/architecture-review-checklist.md` | Structured checklist for architecture reviews and system design sessions |

## When to Read Each File

**Architecture review / system design:**
Start with `architecture-review-checklist.md`, then read the relevant style or pattern file for deeper context.

**Choosing an architectural style:**
Read `architectural-styles-monolithic.md` or `architectural-styles-distributed.md` (or both) and compare the trade-off summary table.

**Designing a new service or component:**
Read `architectural-patterns.md` (hexagonal for internal structure, CQRS/event sourcing for complex domains).

**Integration between systems:**
Read `enterprise-patterns.md` (integration section) for the four integration approaches.

**Documenting architectural decisions:**
Read `fundamentals.md` for ADR and Architecture Haiku templates.

## Architectural Style Quick Comparison

```
Style             | Type        | Scalability | Complexity | Best For
──────────────────┼─────────────┼─────────────┼────────────┼───────────────────────────
Layered           | Monolithic  | Low         | Low        | Small/medium business apps
Pipeline          | Monolithic  | Low         | Low        | Data processing, ETL
Microkernel       | Monolithic  | Low         | Medium     | Product apps, plugin systems
Event-Driven      | Distributed | High        | High       | Async, decoupled workflows
SOA               | Distributed | Medium      | High       | Enterprise integration
Microservices     | Distributed | High        | Very High  | Independent team/domain scale
```

## Quality Attribute → Style/Pattern Lookup

| Need | Consider |
|------|---------|
| Independent deployability | Microservices |
| Extensibility / plugin model | Microkernel |
| High throughput data processing | Pipeline |
| Async decoupling | Event-Driven Architecture |
| Complex read/write scaling | CQRS |
| Full audit trail | Event Sourcing |
| Testable business logic isolated from infra | Hexagonal |
| Simple team-owned service | Layered |
