Querying the File 1

چکیده
We show how structured data stored in les can beneet from standard database technology and in particular be queried and updated using database languages. We introduce the notion of structuring schema which consists of a grammar annotated with database programs and of a database schema. We study the translation from structured strings to databases, and the converse. We adapt optimization techniques from relational databases to our context.

Developing a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملA Map-Reduce algorithm for querying linked data based on query decomposition into stars
In this paper, we investigate the problem of e cient querying large amount of linked data using Map-Reduce framework. We assume data graphs that are arbitrarily partitioned in the distributed file system. Our technique focuses on the decomposition of the query posed by the user, which is given in the form of a query graph into star subqueries. We propose a two-phase, scalable Map-Reduce algorit...
متن کاملExtended File System Metadata Management with Relational Databases
Modern file systems need to handle extended metadata. Existing file systems are not equipped to handle managing metadata in the amount of files and the diversity of files that these file systems are now supporting. Users need better searching and querying capabilities. Metadata within files still remain applicationand file format-specific and is often proprietary, which makes searching difficul...

The Linking File System introduces a new storage paradigm for enhanced user productivity through relationships between files, yet it opens up new challenges in usability. LiFSBrowse is a GUI for LiFS that attempts to meet those challenges through giving customizable graphical views of the file system. LiFSBrowse supports interaction through link manipulation and file system querying. We describ...
متن کاملMelting Pot XML: Bringing File Systems and Databases One Step Closer
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-awar...
متن کاملA File System Based on Concept Analysis
We present the design of a le system whose organization is based on Concept Analysis à la WilleGanter . The aim is to combine querying and navigation facilities in one formalism. The le system is supposed to o er a standard interface but the interpretation of common notions like directories is new. The contents of a le system is interpreted as a Formal Context, directories as Formal Concepts, a...
