XQBE: A Graphical Interface for XQuery Engines [chapter]

Daniele Braga, Alessandro Campi, Stefano Ceri
2004 Lecture Notes in Computer Science  
We designed and implemented XQBE, a visual dialect of XQuery that uses hierarchical structures, coherent with the hierarchical nature of XML, to denote the input and output documents.  ...  XQuery is increasingly popular among computer scientists with a SQL background, since queries in XQuery and SQL require comparable skills to be formulated.  ...  The contribution of our work is the availability of an environment in which users can query XML data with a GUI, access the generated XQuery statement, and also visualize the XQBE version of a large class  ...

A graphical environment to query XML data with XQuery

D. Braga, A. Campi
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417)  
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.  ...  With this motivation in mind, we designed XQBE, a dialect of XQuery inspired by the QBE language (Query by Example).  ...  The graphical constructs and the graphs themselves are internally represented as XML data. XQBE queries can also be saved and exported as XML data.  ...

A survey of graphical query languages for XML data

Mourad Ykhlef, Sarra Alqahtani
2011 Journal of King Saud University: Computer and Information Sciences  
In this article, we will survey some of graphical query languages for querying and restructuring XML data.  ...  XML is fast emerging as the dominant standard for information exchange on the World Wide Web. The ability to intelligently query XML data becomes increasingly important.  ...  GQLX query GQLX is a graphical query language for G-XML data model. A GQLX query can be applied either to a single XML document or to a set of documents.  ...

A Graphical XQuery Language Using Nested Windows [chapter]

Zheng Qin, Benjamin Bin Yao, Yingbin Liu, Michael McCool
2004 Lecture Notes in Computer Science  
This graphical language provides a powerful and user-friendly environment for non-technical users to perform queries.  ...  A graphical XQuery-based language using nested windows, GXQL, is presented. Definitions of both syntax and semantics are provided.  ...  A recent graphical XQuery-based language, XQBE (XQuery By Example) [1] , extends XML-GL to XQuery, and also overcomes some limitations of XML-GL.  ...

A Survey on Visual Query Systems in the Web Era (extended version) [article]

Jorge Lloret-Gazo
2017 arXiv   pre-print
In 1996, a paper by Catarci reviewed the Visual Query Systems available until that year.  ...  As more and more collections of data are becoming available on the web to everyone, non expert users demand easy ways to retrieve data from these collections.  ...  Paper [8] presents XQBE, a tool for querying XML data. The XML schema or DTD specification is offered to the user as a starting point for specifying queries in a navigational way.  ...

LiXQuery

2005 SIGMOD record  
XQuery is considered to become the standard query language for XML documents. However, the complete XQuery syntax and semantics seem too complicated for research and educational purposes.  ...  By defining a concise backwards compatible subset of XQuery with a complete formal description, we provide a practical foundation for XQuery research.  ...  For example, the language XQBE [8] (XQuery By Example) is a powerful graphical query language for XML with a well-defined formal semantics.  ...

Pattern by example

Véronique Benzaken, Giuseppe Castagna, Dario Colazzo, Cédric Miachon
2008 Proceedings of the 10th international ACM SIGPLAN symposium on Principles and practice of declarative programming - PPDP '08  
We present Pattern-by-Example (PBE), a graphical language that allows users with little or no knowledge of pattern-matching and functional programming to define complex and optimized queries on XML documents  ...  First, it generates queries that are provably correct with respect to types: the type of the result is displayed to the user and this constitutes a first and immediate visual check of the semantic correctness  ...  In the context of XML, many attempts to define graphical query languages have been proposed: QSByE (Querying Semi-structured data by Example) [11] , XQBE [6] , Miro-web [5] , EQUIX [9] , BBQ [14]  ...

AQBE — QBE Style Queries for Archetyped Data

Shelly SACHDEVA, Daigo YAGINUMA, Wanming CHU, Subhash BHALLA
2012 IEICE transactions on information and systems  
It proposes a step-by-step graphical query interface to allow semi-skilled users to write queries.  ...  Its aim is to decrease user effort and communication ambiguities, and increase user friendliness. key words: query interfaces, database query languages, electronic health records, healthcare, archetype-based  ...  Thus, these approaches provide inadequate support to express a query. It has also been examined to use XQBE [7] interface directly over the XML description of archetype [20] .  ...

by a query but implicitly by various mappings so as to avoid data loss and duplicates generated by joins.  ...  Close to the concept of universal relation, it extends it in mainly two ways: (i) the input is not a relational schema but a potentially large set of XML data guides; (ii) the view is not defined explicitly  ...  Systems like XQBE [1] and Xing [6] use visual specification of XML queries based on tree patterns.  ...

XA2C: a framework for manipulating XML data

Gilbert Tekli, Richard Chbeir, Jacques Fayolle
2011 International Journal of Web Information Systems  
Data communicated over these domains is now mainly based on XML. Thus, allowing non-expert programmers to manipulate and control their XML data is essential.  ...  unified yet, and (ii) Mashups, which are not formally defined yet and are not specific to XML data, and XML-oriented visual languages are based on structural transformations and data extraction mainly  ...  They are mainly designed for data circulating on the web. Their objective is to target non-expert users; therefore a graphical interface is generally offered to the user to express most operations.  ...

The end-user does not need to know a programming language, a query language or the database schema. Eighth International Conference on Web Engineering 978-0-7695-3261-5/08 $25.00  ...  The main idea is to interactively build an example document, representative of the program output. The system infers from this document, without ambiguity, the publishing program.  ...  The "by example" paradigm has been adapted and extended to semi-structured data and XML document by many proposals: QSByE [4] , QURSED [8] and XQBE [2] .  ...

A Graph-Based Approach to Transform XML Documents [chapter]

Gabriele Taentzer, Giovanni Toffetti Carughi
2006 Lecture Notes in Computer Science  
XML is used as format to e.g. render data, query documents, deal with Web services, generate code from a model or perform model transformation.  ...  As XML diffusion keeps increasing, it is today common practice for most developers to deal with XML parsing and transformation.  ...  XQBE (XQuery by example [4] ) provides a visual language to specify queries on XML documents and translates it into XQuery or XSLT.  ...
