Requirements analysis:

(1) business model à concept model-> design model

Business model: from requirements

Business Use case:

What’s use case, not a step:

(1) meaningful for user

(2) from actor

(3) It’s an abstraction from reality

There are 3 relationships between use cases: implement, include, extend

There are some diagrams for requirements analysis:

Activity diagram:

Sequence diagram:

Collaboration digram:

Concept model: what it should be

Concept use case:

Design model: how to do it

Mapping to implementation: languages, communication protocol,

Logical, development view, deployment view,

What impressed me most?

(1) boundary

(2) Analysis mode: entity, control, boundary

(3) Architecture: business architecture, technical architecture, architecture patterns( MVC, layered, micro kennel)

System thinking vs structural thinking to build a system
