SafArchie Studio

About


What is SafArchie Studio ?

SafArchie Studio is a set of modules for ArgoUML. It transforms ArgoUML into an IDE for software architectures.

SafArchie studio uses seven modules linked together for modelling:

  • Software architecture types,
  • Logical software architectures,
  • Physical architectures,
  • Technical concern architectures
  • Integration rules of a concern (adaptor)
  • Weaving rules for integrating one technical concern into a software architecture

The last modules allows the supervising of software architectures at runtime.

The software architecture description can be used as a blueprint for code generation. There is a projection onto Fractal.

SafArchie Studio is the implantation of the research work done by Olivier Barais for his PhD's thesis. This thesis took place in the Jacquard INRIA project.

Overview of the thesis

Software architecture specification

SafArchie provides a language and a set of tools for describing software architecture. In SafArchie, we argue that, in order to accrue the true benefits of software architecture approaches, one may need to use an architecture centric approach with a global reasoning: from software architecture design to software architecture management to software architecture building, deployment and refinement. However some degree of consistency must be preserved between these different steps of the software life cycle. For this reason, we have based our approach on the notion of architecture types that are points of reference at each step of our reasoning. We offer with SafArchie Studio, a first architecture centric approach which is based on a three-view perspective and driven by the component life cycle.

Software architecture evolution

The SafArchie approach serves as the building blocks of an other project named TranSAT (Transformation of Software ArchiTecture). Indeed, most of the time, software architecture models do not allow new software system features to be added or modified. Thus adding new concerns in a software architecture is difficult and often requires lots of efforts from the architect. Furthermore, the current software architecture models do not provide any means to describe, save, or analyze integration rules of technical concern. TranSAT addresses these lacks of software architecture models. It proposes a framework for designing software architecture through step by step refinements: From an architecture that contains only business concerns to a global architecture that contains business and technical concerns. The main idea of this project is inspired by the Aspect Oriented Software Development (AOSD) concepts.

TranSAT provides three main features:

  • It defines a mechanism to add new concerns to a software architecture specification.
  • It provides a description model for software architecture, which records the integration rules of a specific concern.
  • It specifies rules, which guarantee the correct integration of a technical concern into a business model.

Associated with TranSAT, SafArchie provides an architecture centric approach to build consistent software step by step.
