A new Graphical Query Language for Retrieving Telecommunication Data.

XML is fast emerging as a standard for data representation and exchange on the World Wide Web. So, the ability to efficiently query XML data becomes increasingly important. The telecommunications industry has not yet established an official markup language for data management, but is rapidly moving toward XML as a technology of choice as are other industries. In this paper, we propose a new graphical query language for querying and restructuring telecommunication XML data, which we call GQLX. GQLX is developed on the base of G-XML data model. The paper presents the asic capabilities of GQLX through a sequence of examples of increasing complexity. We also discuss some complex queries illustrating the use of grouping and aggregate functions in GQLX
