XML-OGL: UML-Based Graphical Web Query Language for XML Documents

摘要

The widespread use of XML for standard semi-structured documents on the Web opens up challenging opportunities for Web query language. The UML is a graphical language which represents the result of an object-oriented analysis and design. In this paper, we introduce the UML-based graphical web query language for XML documents. The use of a visual formalism represents the syntax and semantics of queries which enables an intuitive expression of queries, even when they are rather complex. And, it matches a series of processes to store and retrieve XML documents to OODBMS with the use of an uniform visualization for representing both the content of XML documents (and of their DTD) and the syntax and semantics of queries.
