Paper Abstract:
|
The Unified Modeling Language (UML) is extended to model web applications. Meanwhile, Web technology becomes
heavily relies on XML documents. The structure of XML documents, namely the XML Schema or Document Type
Definition (DTD) for these documents can be modeled using UML data structures. UML tools are usually concerned with
the generation of the structure and behavior of the system that is captured by models in their equivalents in the selected
platform. In this paper we introduce a novel approach for the integration between UML and XML families of
technologies. We model the structure of XML using UML class diagrams and based on this, we study how queries for
XML documents, namely XQuery expressions can be described using UML techniques. We show that modeling of XML
documents and its queries represented by XQuery expressions is possible using the querying capabilities of UML Class
diagram and the Object Constraint Language (OCL). As a result, we see how these two technologies compare, what the
advantages of both technologies are and how they can be combined. |
