BaseX – Processing and Visualizing large XML Instances
- AG Scholl (Database and Information Systems)
(2013): Fine Granular Locking in XML Databases |
XML databases gained highly in popularity over the last years, and queries performed got far more complex. Whereas mainly used for single threaded, often single user applications, usage for real-time, multi-user and parallel client-server environments increases. Along with that, demand for higher concurrency gets louder. Origin (projects) |

XML and state-of-the-art XML database management systems (XML-DBMSs) can play a leading role in far more application domains as it is currently the case. Origin (projects) |

(2011): BaseX Tree View : Entwicklung einer datenbankgestützten Visualisierung von XML-Dokumenten |
Diese Arbeit dokumentiert die Entwicklung einer traditionellen Baumvisualisierung, welche als Projekt zur XML-Datenbank BaseX und deren graphischem Frontend, der BaseX GUI, entstand. Zielsetzung dabei war es eine performante Visualisierung zu realisieren, die dem Anwender eine alternative Sicht auf eingelesene XML-Dokumente ermöglicht. Origin (projects) |

BaseX is an early adopter of the upcoming XQuery Full Text Recommendation. This paper presents some of the enhancements made to the XML database to fully support the language extensions. The system s data and index structures are described, and implementation details are given on the XQuery compiler, which supports sequential scanning, index-based, and hybrid processing of full-text queries. Experimental analysis and an insight into visual result presentation of query results conclude the presentation. Origin (projects) |

Ever-growing data volumes demand for storage systems beyond current file systems abilities, particularly, a powerful querying capability. With the rise of XML, the database community has been challenged by semi-structured data processing, enhancing their field of activity. Since file systems are structured hierarchically they can be mapped to XML and as such stored in and queried by an XML-aware database. We provide an evaluation of a state-of-the-art XML-aware database implementing a file system. Origin (projects) |

XML documents are widely used as a generic container for textual contents. As they are increasingly growing in size, XML databases are emerging to efficiently store and query their contents. Besides, due to the hierarchic structure of XML documents, hierarchic visualizations are needed to facilitiate cognitive access to query results. BaseX is a simple database prototype, mapping XML documents to a table based tree encoding. An integrated treemap visualization and a query interface allow visual access to the documents and demonstrate the efficiency of the underlying data storage. Origin (projects) |

(2006): Pushing XPath Accelerator to its Limits Proceedings of the First International Workshop on Performance and Evaluation of Data Management Systems (EXPDB 2006). - Chicago, Ill. : ACM, 2006. Chicago: ACM, 2006 |
Two competing encoding concepts are known to scale well with growing amounts of XML data: XPath Accelerator encoding implemented by MonetDB for in-memory documents and X-Hive's Persistent DOM for on-disk storage. We identified two ways to improve XPath Accelerator and present prototypes for the respective techniques: BaseX boosts in-memory performance with optimized data and value index structures while Idefix introduces native block-oriented persistence with logarithmic update behavior for true scalability, overcoming main-memory constraints.
