Using UML Models to Describe the VISIR System

Razwan Mohmed Salah, Gustavo R. Alves, Pedro Guerreiro, Ingvar Gustavsson


Analysis and design are important phases in the system development lifecycle. In these phases, developers record information necessary for properly understanding the nature of the systems under consideration.

We consider a particular type of system, named Remote Lab that allows both teachers and students to perform real experiments over the internet and we focus on Virtual Instrument Systems in Reality (VISIR). 

We describe a summarized web interface of VISIR using the Unified Modeling Language (UML). Our case study aims at identifying the requirements of VISIR and at creating a set of UML diagrams that succinctly provide enough information to both developers and users so that they acquire enough information for building a general understanding of it.

 Additionally, we provide elements for extending UML to better support further user interface development in VISIR.
