Vassilis Christophides, Martin Dörr, Irene Fundulaki
1997 Lecture Notes in Computer Science  
SIS is a persistent storage system, o ering transaction management and concurrency control, which is based on an object-oriented semantic network data model 30 .  ...  Using instead unconstrained, extensible schemata o ered by object-oriented semantic network systems, we are able both to map document speci c structures as database classes, and to model the associated  ...  The semi-structured" mapping we present bene ts from the expressive p o wer and exibility of data declarations in the SIS and combines the advantages of both approaches using a generic mapping at the metalevel  ...

Graph data models, query languages and programming paradigms

Alin Deutsch, Yannis Papakonstantinou
2018 Proceedings of the VLDB Endowment  
Numerous databases support semi-structured, schemaless and heterogeneous data, typically in the form of graphs (often restricted to trees and nested data).  ...  Incompatibility with SQL presents a learning challenge for graph databases, while table orientation often leads to cumbersome syntactic/semantic structures that are contrary to graph data.  ...  They impede progress towards declarative languages and systems for querying semi-structured data.  ...

A query language for analyzing networks

Anton Dries, Siegfried Nijssen, Luc De Raedt
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
This paper wants to alleviate this situation by proposing a data model and a query language for facilitating the analysis of networks.  ...  With more and more large networks becoming available, mining and querying such networks are increasingly important tasks which are not being supported by database models and querying languages.  ...  This system forms the basis of a large group of other graph-oriented object data models such as Gram [1] and GDM [9] .  ...

Compilation of Query Languages into MapReduce

Caetano Sauer, Theo Härder
2013 Datenbank-Spektrum  
Furthermore, we provide a qualitative evaluation of how recent query languages overcome these restrictions.  ...  Having established the desired characteristics of a query language, we provide an abstract description of the compilation into the MapReduce programming model, which, up to minor variations, is essentially  ...  on the bulk type, and this is a key characteristic that enables the flexible, graph-oriented, and semi-declarative style mentioned earlier.  ...

BiQL: A Query Language for Analyzing Information Networks [chapter]

Anton Dries, Siegfried Nijssen, Luc De Raedt
2012 Lecture Notes in Computer Science  
The BiQL data model consists of two parts: a data model describing objects, link, domains and networks, and a query language describing basic network manipulations.  ...  Surprisingly, tools for querying graph and network databases are much less well developed than for relational data, and only recently an increasing number of studies are devoted to graph or network databases  ...  They use a semi-structured data model to query graph networks in heterogenous web environments; support for creating new nodes and flexible contexts is not provided.  ...

Taxonomy and synthesis of Web services querying languages [article]

Ibrahim El Bitar, Fatima Zahra Belouadha, Ounsa Roudies
2012 arXiv   pre-print
It must also be mutually simple and imposes no restrictions or at least not too many constraints in terms of prior knowledge to use and also provide a formal or semi-formal queries presentation to support  ...  However, these queries cannot be processed by ensuring a high level of performance without being adequately represented first. To this end, different query languages were designed.  ...  These queries can thus express, with specific graphs, location, position or objects orientation constraints.  ...

Statistical Database Query Languages

1985 IEEE Transactions on Software Engineering  
This paper surveys the existing and proposed SDB data definition and data manipulation (i.e., query) languages.  ...  A statistical database management system (SDBMS) may be defined as a database management system that provides capabilities 1) to model, store, and manipulate data in a manner suitable for the needs of  ...  ABE [28] is a screen-oriented language similar to Query-by-Example (QBE) [64] .  ...

ActiveRDF: Embedding Semantic Web data into object-oriented languages

Eyal Oren, Benjamin Heitmann, Stefan Decker
2008 Journal of Web Semantics  
We develop a mapping approach that embeds Semantic Web data into object-oriented languages and thereby enables reuse of existing Web application frameworks.  ...  We present ActiveRDF, an object-oriented API for managing RDF data that offers full manipulation and querying of RDF data, does not rely on a schema and fully conforms to RDF(S) semantics.  ...  These approaches are based on a statically-typed object-oriented language and thus encounter exactly the discussed mismatches: they do not fully account for the flexible and semi-structured nature of RDF  ...

Language Integrated Query as a Canonical Data Model for Virtual Data Integration

Vladimir Klyuchikov
2019 International Conference on Data Analytics and Management in Data Intensive Domains  
Data models of the classes differ a lot, for instance, relational models are applied for structured data, and NoSQL models mostly applied for semi-structured data.  ...  For the issues of data integration it is required to find a model that can unify relational and NoSQL models. A candidate for such unifying data model is Language Integrated Query -LINQ.  ...  Acknowledgements This work is supervised by Sergey Stupnikov, lead research scientist at the Federal Research Center "Computer Science and Control" of Russian Academy of Sciences.  ...

Data Annotation Models And Annotation Query Language

Neerja Bhatnagar, Benjoe A. Juliano, Renee S. Renner
2007 Zenodo  
This paper also presents an SQL-like query language, named Annotation Query Language (AnQL), to query annotation documents.  ...  These models do not require any structural and schematic changes to the underlying database. These models are also flexible, extensible, customizable, database-neutral, and platform-independent.  ...  A data annotation graph is a special graph structured especially for AnQL query processing and is modeled in spirit of the XQuery data model [10] .  ...

Query languages for graph databases

Peter T. Wood
2012 SIGMOD record  
With much current data, such as linked data on the Web and social network data, being graph-structured, there has been a recent resurgence in interest in graph query languages.  ...  We provide a brief survey of many of the graph query languages that have been proposed, focussing on the core functionality provided in these languages.  ...  Acknowledgements I would like to dedicate this survey to the memory of Alberto Mendelzon, whose insight and vision inspired me to investigate graph query languages some 25 years ago.  ...

Performance of graph query languages

Florian Holzschuher, René Peinl
2013 Proceedings of the Joint EDBT/ICDT 2013 Workshops on - EDBT '13  
The results show that the graph-based back-end can match and even outperform the traditional JPA implementation and that Cypher is a promising candidate for a standard graph query language, but still leaves  ...  In this paper we describe our experiences with a different back-end based on the graph database Neo4j and compare the alternatives for querying data with each other and the JPA-based sample back-end running  ...  Soon after a new type of database system arose, a query language was invented to query data in the respective format, e. g., XPath and XQuery for XML databases [11] , OQL for object-oriented databases  ...

1999 Journal of computer and system sciences (Print)  
We extend Chandra and Harel's seminal work on computable queries for relational databases to a setting in which also spatial data may bepresent, using a constraint-based data model.  ...  Concretely, we introduce bothcoordinate-based and point-based query languages that are complete in the sense that they can express precisely all computable queries that are generic with respect to certain  ...  Acknowledgments The authors wish to thank Jan Paredaens and Bart Kuijpers for interesting discussions related to generic geometric queries.  ...
