Architecture & Design

Segments: SADS Foundations

Segment 1: Architectural Fundamentals

• Components, Connectors, and Configurations
• Structural vs. Behavioral Documentation
• Modularity, Cohesion, and Coupling

Segment 2: Design Principles & SOLID

• Single Responsibility, Open-Closed, Liskov Substitution
• Interface Segregation, Dependency Inversion
• GRASP Patterns and Law of Demeter

Segment 3: Architectural Patterns

• Layered, Hexagonal (Ports & Adapters)
• Microservices, Event-Driven, Microkernel
• Serverless and Cloud-Native Topologies

Segment 4: Domain-Driven Design (DDD)

• Strategic Design: Bounded Contexts, Context Mapping
• Tactical Design: Aggregates, Entities, Value Objects
• Ubiquitous Language and Domain Modeling

Segment 5: Quality Attributes & Trade-offs

• Performance, Scalability, Availability
• Security, Maintainability, Usability
• The CAP Theorem and Distributed Trade-offs

Segment Segment 6: Decision Records (ADR)

• Capturing Context and Options
• Documenting Rationale and Consequences
• Managing Decisions as Code

Segment 7: Implementation & Refactoring

• From Design to Code Mapping
• Architecture Review Techniques
• Managing Technical Debt from a Design Perspective

Segment 8: Advanced Concepts

• Reactive Systems Architecture
• Polyglot Persistence Strategies
• Evolutionary Architecture Dynamics

Segment 9: Case Studies

• Scaling Global Interconnects
• High-Volume Messaging Platforms
• Real-time Industrial Control Systems

In-Scope / Out-of-Scope

• In-Scope: Conceptual design, structural patterns, DDD, and ADRs.
• Out-of-Scope: Specific framework tutorials (e.g., Spring Boot specifics), low-level coding without design context.
