Resumen
The article presents information on the use of Unified Modeling Language (UML) in the modeling of Web applications. Web applications are software-intensive systems that are becoming more complex, and are inserting themselves in more mission-critical roles, one way to manage complexity in software systems is to abstract and model them. UML is the standard modeling language for software-intensive systems. This article is intended as an introduction to the issues and possible solutions for modeling Web applications. It focuses on the architecturally significant components particular to Web applications and how to model them with UML. A first version of a formal extension to the UML for Web applications is near completion. This extension will provide a common way for architects and designers to express the entirety of their Web applications design with UML. The most recent information on this extension can be found on the Internet in the Rose and UML sections of Rational Software Corp.'s Web site, www.rational.com.
