Design and implementation of a graphical interface to XQuery

2005

Abstract The spreading of XML data in many contexts of modern computing infrastructures and systems causes a pressing need for adequate XML querying capabilities; to address this need, the W3C is proposing XQuery as the standard query language for XML, with a language paradigm and a syntactic flavor comparable to the SQL relational language. XQuery is designed for meeting the requirements of skilled database programmers; its inherent complexity makes the new language unsuited to unskilled users.

Abstract XQuery, the standard query language for XML, is increasingly popular among computer scientists with a SQL background, since queries in XQuery and SQL require comparable skills to be formulated. However, the number of these experts is limited, and the availability of easier XQuery" dialects" could be extremely valuable. With this motivation in mind, we designed XQBE, a dialect of XQuery inspired by the QBE language (query by example).

In this paper, we propose a solution of XML graphical querying based on the XQuery language. Our proposal integrates textual, spatial and temporal metadata in order to improve information retrieve and present document suitable to th eu ser's needs. We, also, p ...

In the context of our research project, we propose an interactive tool (GuessXQ) to perform the access to the information in a collection of eXtensible Markup Language (XML) documents. Due to the complex nature of those structured documents, the associated standard query language is also complex and, thus, not easy for most of the users. The GUI we propose does not require any knowledge about the query language, it is based on the Query-By-Example (QBE) paradigm from traditional databases. Using QBE, instead of specifying the desired components of the documents and eventual restrictions in a query, the user exemplifies those components marking them directly on a sample document picked-up from the collection. We believe this leverages the user's cognition about the object to search. GuessXQ is then responsible for the generation of the query to be treated by the information retrieval engine.

XQuery is increasingly popular among computer scientists with a SQL background, since queries in XQuery and SQL require comparable skills to be formulated. However, the number of these experts is limited, and the availability of easier XQuery “dialects” could be extremely valuable. Something similar happened with QBE, initially proposed as an alternative to SQL, that has then become popular as the user-friendly query language supported by MS Access.
