Study Notes

Introduction to Software Architecture

Software architecture is crucial for successful software system development.
Every software system is designed to meet organizational business goals.
Software architecture bridges the gap between abstract business goals and the final, concrete system.
Architecture can be designed, analyzed, and documented using established techniques to support achieving business goals.
Architectural design, analysis, and documentation focus on achieving business goals, considering influences like business goals leading to quality requirements.

What Software Architecture Is and Isn't

Software architecture defines the structures needed to understand a system.
These structures include software components, their relationships, and their properties.
Architecture focuses on enabling reasoning about the system.
A key characteristic of architecture is its abstraction from unnecessary details, omitting information irrelevant to high-level understanding.
Focusing on public interfaces simplifies architectural analysis.
Architectural decisions should not be viewed through trial or error but a deliberate approach based on the system's requirements

Architectural Structures and Views

Architectural structures have counterparts in the real world, like different views of the human body (neurology, orthopedics).
Different perspectives, even though distinct, are interrelated to provide a holistic view.
Similar concepts apply to software architecture.

Three Kinds of Structures

1. Component-and-Connector (C&C) Structures

Focuses on how software components interact during runtime.
Describes the structure as a collection of components and their interactions (connectors).
Components may be services, peers, clients, servers, filters, etc.

2. Module Structures

Partitions systems into implementation units (modules).
Modules have specific computational tasks and are often assigned to developers.
Implementations can include packages, classes, or layers.
Module structure depicts relationships between modules (using, extending, containing).

3. Allocation Structures

Maps software structures to non-software aspects (organization, development environment, testing).
Identifies the hardware and environment used (processors, directories).
Details assignments to development or execution teams.

System Architecture

A system's architecture involves mapping functionality to hardware and software components and human interaction.
It considers the complete system (hardware, software, and human interaction).
A system architecture affects aspects like functionality assigned to processors, and network types.
Provides reasoning about qualities like performance and reliability.
A description of the system architecture allows reasoning about qualities like power consumption and physical dimensions.

Enterprise Architecture

Describes an organization's structure, processes, information flow, and personnel.
Essential for modern businesses needing information system support.
Focuses on how software systems support business processes and goals.
Typically includes processes deciding which systems should exist within a business.
Includes external system interaction and data model considerations.
Software infrastructure is sometimes considered part of the enterprise architecture.
