A Survey of Software Architecture Viewpoint Models and StandardNotations

Surveyed five similar approaches to documenting software architecture

A Survey of Software  Architecture Viewpoint Models 


(----------- Key Points Only ----------)

 

Overview

 

                Surveyed five similar approaches to documenting software architecture

 

 

                To identify:

 

Their strengths and weaknesses

 

An optimum approach to documenting software architecture

                                    Rationale                                                                                                                                                                                                   = Non-Functional Requirements

 

 

 

Survey

 

 

                                       Framework

 

based on IEEE 1471-2000, IEEE (2000).

 

                                       Viewpoint Models:

 

“4+1” View Model, Kruchten, P. (1997).

 

SEI View Model,                                                                                                                                                                                                                                                                                                         Clements, P. et al. (2002b).

 

ISO RM-ODP, ISO (1994).

 

Siemens Four View Model, Soni, D. et al. (1995).

 

Rational ADS, Norris, D. (2004).

 

 

 

Survey - Comparison Framework

 

 

          Stakeholders

eg. Architects, Testers, Managers.

 

from “Documenting Software Architectures: views and beyond” (Clements et al, 2002a, page 10).

 

 

 

          Concerns

eg. Performance, Implementation, Privacy.

 

from “Software Engineering” (Sommerville, 2000, page 101).

 

 

          Structures
