Abstract

XML and XQuery provide a convenient way to model, store, retrieve and process data. As a result, XML databases have become more and more popular in recent years. Consequently, their usage scenarios have gone far beyond handling XML exclusively.

This thesis focuses on the challenges which emerge from unifying the input and output processing of data in XML databases. Based on the analysis of use cases and existing solutions, we define several requirements which shall be met for generalized data processing. Following those we introduce a generic framework, which can serve as a blueprint when designing the input and output data flow in an XML database. Furthermore, we propose a solution how this framework can be applied in an existing open source XML database, named BaseX, in order to improve its current approach of data processing.

Summary in another language

Die flexible und standardbasierte Modellierung, Speicherung, Abfrage und Verarbeitung von semistrukturierten Daten sind die häufigsten Beweggründe für den Einsatz von XML Technologien. Stetig wachsende Datenmengen steigern dabei nicht nur die Popularität von XML Datenbanken, sondern stellen neue Voraussetzungen für die Implementierungen: viele Anwendungen erfordern mehr als nur die Speicherung von Daten die originär in XML vorliegen.

Diese Arbeit untersucht die Herausforderungen bei der Umsetzung von einheitlichen Ein- und Ausgabeschnittstellen in XML Datenbanken. Nach einer Analyse bestehender Implementierungen und verschiedener Anwendungsszenarien stellen wir Anforderungen an Im- und Exportschnittstellen fest. Basierend auf diesen Überlegungen definieren wir ein generisches Framework zur Implementierung von Ein- und Ausgabe in XML Datenbanken. Schließlich stellen wir aus, wie man das Framework in BaseX, einem Open Source XML Datenbankmanagementsystem, umsetzen kann.
