Extending Datalog to cover XQuery
Datalog is a traditional platform in database research and, due to its ability to comprehend recursion, it seems to be a good choice for modeling XQuery. Unfortunately, XQuery functions have arguments carrying sequences; therefore, logic-based models of XQuery must be second-order languages and, consequently, Datalog is usually extended by node-set variables. In this paper, we suggest an altern...
متن کاملUsing Genome Query Language (GQL) to uncover genetic variation
Motivation:With high throughput DNA sequencing costs dropping below $1, 000 for human genomes, data storage, retrieval, and analysis are the major bottlenecks in biological studies. In order to address the large-data challenges, we advocate a clean separation between the evidence collection and the inference in variant calling. We define and implement a Genome Query Language (GQL) that allows f...
متن کاملExtending XQuery with Window Functions
This paper presents two extensions for XQuery. The first extension allows the definition and processing of different kinds of windows over an input sequence; i.e., tumbling, sliding, and landmark windows. The second extension extends the XQuery data model (XDM) to support infinite sequences. This extension makes it possible to use XQuery as a language for continuous queries. Both extensions hav...
متن کاملIntensional Query Answering to XQuery Expressions
XML is a representation of data which may require huge amounts of storage space and query processing time. Summarized representations of XML data provide succinct information which can be directly queried, either when fast yet approximate answers are sufficient, or when the actual dataset is not available. In this work we show which kinds of XQuery expressions admit a partial answer by using as...
متن کاملMapping Network Relationships from Spatial Database Schemas to GML Documents
Spatial data encoded in GML documents are used in various applications and are especially suited to storing, manipulating and exchanging geographic information. However, a large share of currently available spatial data is stored in spatial databases. This article presents a method to map arcs and nodes, organized in a network using spatial relationships, from a spatial database to a GML docume...
