Using UML Models to Describe the VISIR System
<p class="Abstract">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.</p><p><strong>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). </strong></p><p><strong>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.</strong></p><strong> Additionally, we provide elements for extending UML to better support further user interface development in VISIR.</strong>
