What is a system architecture document?
A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
How do I create a system architecture document?
How to draw an architectural diagram
- Document your shapes.
- And the edges.
- Keep your arrows consistent.
- Use colors sparingly.
- Use multiple diagrams, if necessary.
- Merge incomplete diagrams.
- Include legends/keys/glossaries.
- Use diagramming software.
How is documentation of software architecture done?
The idea is to use 4 different granularity (or zoom) levels for documenting software architecture:
- Level 1: System Context diagram.
- Level 2: Container diagram.
- Level 3: Component diagram.
- Level 4: Code diagram.
What is system architecture diagram?
An architectural diagram is a diagram of a system that is used to abstract the overall outline of the software system and the relationships, constraints, and boundaries between components. It is an important tool as it provides an overall view of the physical deployment of the software system and its evolution roadmap.
What things are included in a documentation of a software?
Types of documentation include:
- Requirements – Statements that identify attributes, capabilities, characteristics, or qualities of a system.
- Architecture/Design – Overview of software.
- Technical – Documentation of code, algorithms, interfaces, and APIs.
What should be included in a software architecture document?
Provide an overview of the entire Software Architecture Document. Include the scope, definitions, acronyms, abbreviations, references, and overview of this document. Define the role or purpose of the Software Architecture Document as it relates to the overall project documentation. Briefly describe the structure of the document. Scope
What is the purpose of an architectural document?
1. Introduction 1.1 Purpose This document provides a comprehensive architectural overview of the system, using a number of different architectural views to depict different aspects of the system. It is intended to capture and convey the significant architectural decisions which have been made on the system. 1.2 Scope
When to adjust the outline of the software architecture document?
You should adjust the outline of the Software Architecture Documentto suit the nature of your software: Some of the architectural views may be irrelevant: The Deployment View is not needed for single-CPU systems. The Process View is not needed if the system uses only a single thread of control.
What is the role of the software architect?
The software architectis also responsible for maintaining the architectural integrity of the system through the development process by: Approving all changes to architecturally significant elements, such as major interfaces, described in the Software Architecture Document.
