Object-Oriented Wrapper for Semistructured Data in a Data Grid Architecture

Kamil Kuliberda, Jacek Wislicki, Radoslaw Adamus, Kazimierz Subieta
2006 Business Information Systems  
The paper addresses the problem of integrating data based on a XML-like semistructured model with a data grid architecture based on an object-oriented model.  ...  This work is continuation of the previous works on object-to-relational wrappers and covers a generic integrationp rocedure for utilizing a native Lore query mechanism f or retrieving data from X ML data  ...  ) [10, 12] , showing a method for integration of fragmented data into the grid, e.g. how to merge fragmented collections of object data structures where some parts of them are placed in separated l ocal  ...

Path constraints on semistructured and structured data

Peter Buneman, Wenfei Fan, Scott Weinstein
1998 Proceedings of the seventeenth ACM SIGACT-SIGMOD-SIGART symposium on Principles of database systems - PODS '98  
The authors thank Victor Vianu, Val Tannen and Susan Davidson for helpful discussions.  ...  An object-oriented model In this section, we investigate word constraint implication in an object-oriented data model. The data model We rst present the data model.  ...  A proof of the decidability of word constraint implication in semistructured databases was presented in [3] . However, we will show that the proof breaks down in an object-oriented data model.  ...

Managing semistructured data with FLORID: A deductive object-oriented perspective

Bertram Ludäscher, Rainer Himmeröder, Georg Lausen, Wolfgang May, Christian Schlepphorst
1998 Information Systems  
We elaborate on the management of semistructured data and show h o w reachability queries involving general path expressions and the extraction of data paths in the presence of cyclic data can be handled  ...  Techniques for navigating in object-oriented databases can be applied to semistructured databases as well, since the latter may be viewed as very simple instances of the former.  ...  Example 1 Publications Database In Figure 1 , a fragment of an object-oriented publications database is depicted.  ...

XML-based Components for Federating Multiple Heterogeneous Data Sources [chapter]

Georges Gardarin, Fei Sha, Tram Dang Ngoc
1999 Lecture Notes in Computer Science  
The system is composed of four main components: a wrapper generator using rule-based scripting to produce XML data from various source formats, a mediator querying and integrating relational and XML sources  ...  , an XML DBMS extender supporting XML on top of relational DBMSs, and client tools including a Java API and an XML query browser.  ...  Acknowledgments We would like to thank Peter Fankhauser, Dana Florescu, Henri Laude and Patrick Valduriez for helpful discussions, particularly in the context of the MIRO-Web project.  ...

Catching the boat with Strudel

Mary Fernández, Daniela Florescu, Jaewoo Kang, Alon Levy, Dan Suciu
1998 Proceedings of the 1998 ACM SIGMOD international conference on Management of data - SIGMOD '98  
Strudel's key idea is separating the management of the site's data, the creation and management of the site's structure, and the visual presentation of the site's pages.  ...  First, the site builder creates a uniform model of all data available at the site.  ...  Because of the dynamic nature of site and data graph schemas, we conclude that traditional relational and object-oriented model are not appropriate.  ...

Storing semistructured data with STORED

Alin Deutsch, Mary Fernandez, Dan Suciu
1999 Proceedings of the 1999 ACM SIGMOD international conference on Management of data - SIGMOD '99  
Systems for managing and querying semistructured-data sources often store data in proprietary object repositories or in a tagged-text format.  ...  We are interested in applying STORED to XML data, which is an instance of semistructured data.  ...  Object-oriented databases 5] can store SGML and XML documents without explicitly storing their schema, but they require a DTD to derive an object-oriented schema.  ...

A query language for XML

Alin Deutsch, Mary Fernandez, Daniela Florescu, Alon Levy, Dan Suciu
1999 Computer Networks  
An important application of XML is the interchange of electronic data (EDI) between multiple data sources on the Web.  ...  As XML data proliferates on the Web, applications will need to integrate and aggregate data from multiple source and clean and transform data to facilitate exchange.  ...  Researchers have found this data to be fundamentally different from relational or object-oriented data, and called it semistructured data.  ...

2002 Lecture Notes in Computer Science  
We describe our extension to the methodology that makes it applyable in general to product classification standard, by selecting a fragment of ECCMA/UNSPSC and ecl@ss standard.  ...  A marketplace is the place in which the demand and supply of buyers and vendors participating in a business process may meet.  ...  For a conventional structured information source (e.g. relational databases, object oriented databases), schema description is always available and can be directly translated into the common data model  ...

A first step towardsmodeling semistructured data in hybrid multimodal logic

Nicole Bidoit, Serenella Cerrito, Virginie Thion
2004 Journal of Applied Non-Classical Logics  
1) We generalize the notion of schema, by proposing a definition of schema were references are "well typed" (contrary to what happens with DTDs). 2) We formalize semistructured data, schema for semistructured  ...  data and integrity constraints in a unique framework, namely hybrid multimodal logic.  ...  Indeed, an XML document may be seen as a collection of data whose organization is "more flexible" with respect to, for instance, relational or object oriented databases. Why ?  ...

QURSED enables the development of web-based query forms and reports (QFRs) that query and report semistructured XML data, i.e., data that are characterized by nesting, irregularities and structural variance  ...  We describe QURSED and illustrate how it accommodates the intricacies that the semistructured nature of the underlying database introduces.  ...  DataGuide-driven GUI [14] , and PESTO [4] , which target the querying of XML or object-oriented Unlike the form and report generators, which produce web frontends for the "general public", visual querying  ...
