How to Design Architecture?

• 방법론 (Methodology or Process)

• SW Architecture Method에 대한 Knowledgebase
• Architecture Styles (30개)
• Architecture Viewpoints (6~7개)
• Design Tactics for Quality Properties (NFR)

을 함께 이용한다. (둘중 하나라도 없어서는 안된다.)

Architectural Views

• (*) Functional View (Data Manipulation, Logical View)
• (*) Information View (Persistant Data View, Logical View)
• (*) Concurrency View (Behavior or Process View)
• (*) Context View
• Development View
• (*) Deployment View
• Operation View

• A1. Architectural Requirement Refinement
• A2. System Context Analysis (Context View 작성)
• A3. Skeleton Architecture Design 
• Architectural style을 결정하고 사용하는 단계.
• 변경/유지보수의 대상이 아님
• A4. View-Specific Architecture Design
• A5. NFR-Specific Architecture Design
• A6. Architecture Validatation
