User interface modeling within application system development

Abstract

A well-designed user interface, nowadays exclusively graphical, is one of the key factors determining the application's appeal to the user. GUI modeling should be a part of the overall process of application system development. The aim of this article is to show different methodological approaches to the GUI modeling. Nowadays, UML is a widely used standard for object-oriented modeling software in the software industry. The paper investigates whether it is possible to successfully model GUI by using UML and suggests a way in which this can be achieved. by using some UML extensions without disrupting the standardization.
