Research ArticleOpen accessIn the keywordsQuery Pattern-based Relational Data to XML Data Translation AlgorithmJinhyung Kim, Dongwon Jeong, Doo-Kwon BaikThis paper proposes a new query pattern-based relational schema-to-XML schema translation (QP-T) algorithm to resolve implicit referential integrity issue. Various translation methods have been introduced on structural aspects and/or semantic aspects. However, most of conventional methods consider only explicit referential integrities specified by relational schema. It causes several problems such as incorrect transformation, abnormal relational model transition and so on. … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,188 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNormalized Relational Storage for Extensible Markup Language (XML) SchemaKamsuriah Ahmad, Reduan SamadProblem statement: The use of XML as the common formats for representing, exchanging, storing, integrating and accessing data posses many new challenges to database systems. Most of application data are stored in relational databases due to its popularity and rich development experiences over it. Therefore, how to provide a proper mapping approach from XML model to relational model become the … …Journal of Computer Science, Vol. 7, Issue 11 · 24 Aug 2011 · 6,838 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Efficient Middleware for Storing and Querying XML Data in Relational Database Management SystemMohammed Adam Ibrahim Fakheraldien, Jasni Mohamad Zain, Norrozila SulaimanProblem statement: In this study, we propose a middleware that provides a transformation utility for storing and querying XML data in relational databases using model mapping method. Approach: To store XML documents in RDBMS, several mapping approaches can be used. We chose structure independent approach. In this middleware the model mapping method XParent and free of cost available technologies MYSQL, … …Journal of Computer Science, Vol. 7, Issue 2 · 26 Feb 2011 · 7,605 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExtending the Concepts of Normalization from Relational Databases to Extensible-Markup-Language Databases ModelH.J. F. El-SofanyIn this study we have studied the problem of how to extend the concepts of Functional Dependency (FD) and normalization in relational databases to include the eXtensible Markup Language (XML) model. We shown that, like relational databases, XML documents may contain redundant information and this redundancy may cause update anomalies. Furthermore, such problems are caused by certain functional dependencies among … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 6,461 accessesView PDF Cite
