4. Logical Architecture What is an architecture?
An architecture is a set of :-
Selection of the structural elements.
Interfaces by which the system is composed.
Behavior

5. In software development
Noun architecture
Verb architecture
As a noun, the architecture includes—
System behavior.
Responsibilities of systems and subsystems.
Collaborations
As a verb, the architecture is
Investigation
Design
Architectural investigation or Architectural design.

6. Logical Architecture:-
which describes the system in terms of :
Layers
Packages
Major frameworks
Classes
Interfaces
Subsystems.

8. Deployment Architecture:-
Which describes the system in terms of:
The allocation of processes to processing units.
The network configuration.

9. Design with layer’s Note:-
The Layers pattern relates to the logical architecture.
A layer is a large-scale element, often composed of several packages or sub- systems.

Note:-
The purpose and number of layers varies across applications and application domains (information systems, operating systems, and so forth).

11. The Model-View Separation Principle
In this context:
Model is a synonym for the Domain layer of objects.
View is a synonym for presentation objects.
The Model-View Separation principle states that :-
Model (domain) objects should not have direct knowledge of view (presentation) objects, at least as view objects.

13. The motivation for Model-View Separation includes:
To allow separate development of the model and user interface layers.
To minimize the impact of requirements changes in the interface upon the domain layer.
To allow execution of the model layer independent of the user interface layer, such as in a message-processing or batch-mode system.

14. Package Diagram Groups of “basic elements”, e.g., classes or use cases
Can contain other packages, creating hierarch
Represented as file folders

Package & Relations
• Dependencies
• Implementations
• Merges
Dependencies:
Package A depends on package B if A contains a class which depends on a class in B.
• Graphic representation:
> or >
<<use>>

16. Example of Dependencies:
Typical 3-tier application (sketch):

17. Implementations:
Meaningful if multiple variants are present.

18. Merge:
A package merge indicates that the contents of the two packages are to be combined.
