Interactive Poster: Exploring Block Access Patterns of Native XML Storage
نویسندگان
چکیده
Recent block-based native XML storage systems such as IDEFIX touch blocks according to the XQuery engine’s execution plan. The resulting access patterns are virtually unknown and potentially cause many expensive disk seeks. Visualization comes to the rescue when extensive log files must be analyzed – a tedious and difficult task. The dynamic time-based block-touch animation as well as the static block-type information of VISUAL IDEFIX foster the insight into the performance-critical internals of the XML storage and help to optimize both the block layout and the XQuery engine to speed up queries.

XML Data Stores: Emerging Practices
X ML's wide adoption in both academia and industry has revealed a controversial fact. From one perspective, XML is characterized by interoperability, ease of use, and extensibility; from another, it creates difficulties when integrated into existing systems (such as typical database applications and database management systems). One result of this conflict is the arrival of native XML data stor...
متن کاملA clustering method based on path similarities of XML data
Current studies on the storage of XML data are focused on either the efficient mapping of XML data onto an existing RDBMS or the development of a native XML storage. Some native XML storages store each XML node in a parsed object form. Clustering, which means the physical arrangement of objects, can be an important factor in improving the performance in this storage model. In this paper, we pro...
متن کاملA New Design for a Native XML Storage and Indexing Manager
This paper describes the design and implementation of an XML storage manager for fast and interactive XPath expressions evaluation. This storage manager has two main parts: the XML data storage structure and the index over this data. The system is designed in such a way that it minimizes the number of page reads for retrieving any XPath expression results while avoiding the shortcomings of prev...
متن کاملControlling Access to XML Documents over XML Native and Relational Databases
In this paper we investigate the feasibility and efficiency of mapping XML data and access control policies onto relational and native XML databases for storage and querying. We developed a re-annotation algorithm that computes the XPath query which designates the XML nodes to be re-annotated when an update operation occurs. The algorithm uses XPath static analysis and our experimental results ...
متن کاملVisually Exploring and Querying XML with BaseX
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 ...
