Concepts and Principles Functional Architecture Model. It is intended to capture and convey the significant architectural decisions which have been made on the system. Software Architecture Document. We can segregate Software Architecture and Design into two distinct phases: Software Architecture and Software Design. In Architecture, nonfunctional decisions are cast and separated by the functional requirements. In Design, functional requirements are accomplished. The view documents the system’s functional structure-including the key functional elements, their responsibilities, the interfaces they expose, and the interactions between them. The Functional view of a system defines the architectural elements that deliver the system’s functionality. This software architecture template can save many hours in creating great software architecture by using built-in symbols right next to the canvas. Architecture serves as a blueprint for a system. Each structure comprises software elements, relations among them, and properties of both elements and relations. Software architecture refers to the fundamental structures of a software system and the discipline of creating such structures and systems. A functional architecture functional architecture model is a set of functions and their sub-functions that defines the transformations performed by the system to complete its mission.. Function and Input-Output Flow - In the context of System Architecture, functions and input-output flows are architecture entities. Software Architecture Example The easiest way to create a software architecture diagram is editing an existing template. Introduction 1.1 Purpose. The Functional Viewpoint. Providing printing capability is a functional requirement of particular significance to architecture, for example. Software Architecture. 1. This document provides a comprehensive architectural overview of the system, using a number of different architectural views to depict different aspects of the system. Usability, Reliability, Performance, and Supportability Requirements The remaining "URPS" categories describe non-functional requirements that are generally architecturally significant. Examples of web architecture application Let's consider an example of a service with one architectural level (Single Tier) In an application with one architectural level, the user interface, business logic, that is, the backend part of the application and the database are on the same server The architecture of a software system is a metaphor, analogous to the architecture of a building.
