📄 Comprehensive Summary of Chapter 6: Architectural Design

Software Architecture

The identification of subsystems within a system and management of their interactions and communications.

Architectural Design

An early stage of the system design process that bridges the gap between system specification and system design.

Architecture in the Small

Focuses on the structure of individual programs.

Architecture in the Large

Focuses on large enterprise systems involving multiple interconnected programs across different computers.

Logical View

Shows system abstractions as objects or classes.

Process View

Illustrates the interactions of runtime processes.

Development View

Demonstrates the system's organization for development.

Physical View

Describes hardware and software component deployment.

MVC

A design pattern that separates system data, user interface, and interaction logic.

Layered Architecture

Organizes the system into layers, each providing services to the layer above.

Repository Pattern

Centralizes system data in a repository accessible by all components.

Client-Server Architecture

Divides system functionality between servers (service providers) and clients (service requesters).

Pipe and Filter Pattern

Processes data sequentially through discrete transformation stages (filters).

Data Processing Applications

Handle data in batches without user interaction.

Transaction Processing Systems

Manage user requests to retrieve or update data.

Event Processing Systems

React to external events and trigger system actions.

Language Processing Systems

Interpret or compile languages like compilers and interpreters.

4 + 1 Model

A model that includes multiple views (Logical, Process, Development, Physical) and use cases for a comprehensive system architecture.

Architectural Patterns

Proven solutions that enhance reuse across different projects.

Application Architectures

Provide templates and best practices for specific types of systems.

Key Insight of Architectural Design

It is crucial for large systems as it provides a structural backbone for scalability and manageability.
