2. The Importance of Models
A large part of the RUP focuses on modeling.
Models help us understand both the:
problem and
solution.
The model is not the reality but
best models are ones that stick very close to reality

3. Architecture
Suppose the task:
describing a system so that designers, programmers, users, and managers would be able to do the following:
Understand what the system does
Understand how the system works
Be able to work on one piece of the system
Extend the system
Reuse part of the system to build another one

4. Architecture Multiple Views
For a building, different types of blueprints are used to represent different aspects of the architecture:
Floor plans
Elevations
Electrical cabling
Water pipes, central heating, and ventilation
The look of the building in its environment (in sketches)

5. The 4+1 View Model of Architecture

6. The 4+1 View Model of Architecture
The Logical View
It is an abstraction of the design model and identifies:
major design packages/subsystems, and
classes

7. The 4+1 View Model of Architecture

8. The 4+1 View Model of Architecture
The Implementation View
It addresses the issues of
ease of development,
management of software assets,
reuse

9. The 4+1 View Model of Architecture
The Process View
the concurrency and synchronization aspects of the design

12. The 4+1 View Model of Architecture
The Deployment View
Addresses:
how the various executables and other runtime components
are mapped to the underlying platforms or computing nodes.

15. The 4+1 View Model of Architecture
The Use-Case View
It contains a few key scenarios or use cases.
Initially,
are used to drive the discovery and design of the architecture in the inception and elaboration phases,
later
they will be used to validate the different views.

17. An Architecture-Centric Process
RUP defines two artifacts related to architecture:
The software architecture description (SAD),
which describes the architectural views relevant to the project
The architectural prototype,
which serves to validate the architecture and serves as the baseline for the rest of the development

18. An Architecture-Centric Process
These two key artifacts are the roots of three others:
Design guidelines
Product structure
The development environment is based on the implementation view.
Team structure
is based on the structure of the implementation view.
