Graph data models, query languages and programming paradigms

Alin Deutsch, Yannis Papakonstantinou
2018 Proceedings of the VLDB Endowment  
present SQL reductions and extensions that capture the essentials of such database systems.  ...  We cover both declarative query languages, whose semantics is independent of the underlying model of computation, as well as languages with an operational semantics that is more tightly coupled with the  ...  The corresponding plethora of query languages is classified also via reduction to an SQL extension, Configurable Graph SQL.  ...

Semistructured Models, Queries and Algebras in the Big Data Era

Yannis Papakonstantinou
2016 Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16  
In addition to these genuine JSON databases, relational databases also provide special functions and language features for the support of JSON columns, typically piggybacking on non-1NF (non first normal  ...  We refer to SQL databases with JSON support as SQL/JSON databases.  ...  Similarly, when a FROM clause ranges over an array, SQL++ allows a pair of variables to capture the data at an array position and the index of this position.  ...

A natural language interface plug-in for cooperative query answering in biological databases

Hasan M Jamil
2012 BMC Genomics  
In this paper, our goal is to propose a semantic correspondence plug-in to aid natural language query processing over arbitrary biological database schema with an aim to providing cooperative responses  ...  One of the many unique features of biological databases is that the mere existence of a ground data item is not always a precondition for a query response.  ...  The full contents of the supplement are available online at http://www.biomedcentral.com/ bmcgenomics/supplements/13/S3.  ...

Fuzzy Object Oriented Database versus FRDB for Uncertainty Management

Sonia Sonia, Subita Kumari
2013 International Journal of Computer Applications  
It is impossible to capture all of the semantics of real world information and to model it in a perfect way.  ...  So in order to deal with inexactness fuzzy techniques have been extensively integrated with more advanced object oriented database system which is capable to represent and manipulate the complex objects  ...  Fuzzy Relational Databases It is an extension of the relational database. FRDBMS is considered first of all a database.  ...

A Formalization of Metaphors and Image-Schemas in User Interfaces [chapter]

Werner Kuhn, Andrew U. Frank
1991 Cognitive and Linguistic Aspects of Geographic Space  
Numerous proposals have been made to extend the relational database query language SQL to serve as a spatial query language and currently efforts are under way to establish a standardized spatial SQL.  ...  Here it is argued that the SQL framework is inappropriate for an interactivespatial query language and an extended spatial SQL is at best a short-term solution.  ...  to indicate projective relations which are not in Herskovits' set.  ...

How Would You Like to Aggregate Your Temporal Data?

M.H. Bohlen, J. Gamper, C.S. Jensen
2006 Thirteenth International Symposium on Temporal Representation and Reasoning (TIME'06)  
In particular, it provides a general framework of temporal aggregation concepts, and it discusses the abilities of five approaches to the design of temporal query languages with respect to temporal aggregation  ...  Rather than providing focused, polished results, the paper's aim is to explore the inherent support for temporal aggregation in an informal manner that may serve as a foundation for further exploration  ...  Jensen is also an adjunct professor in Department of Technology, Agder University College, Norway.  ...

An ontological approach to describe the SQL:2003 object-relational features

C. Calero, F. Ruiz, A. Baroni, F. Brito e Abreu, M. Piattini
2006 Computer Standards & Interfaces  
The SQL (Structured Query Language) is currently available in most database management systems and is the focus of an intense standardization process resulting in the latest version of the SQL:2003 standard  ...  In this paper we propose an ontology for the object-relational features of the new SQL:2003 standard, formalized with UML 2.0 class diagrams and OCL well-formedness rules.  ...  Ackowledgements The authors thank Prof. Pedro Guerreiro (from FCT/UNL) and the anonymous reviewers for their valuable comments and suggestions.  ...

This has prompted the need for other, different types of databases beyond SQL (Structured Query Language) that have properties of scalability and availability.  ...  NoSQL (Not-Only SQL) databases, mostly with the BASE (Basically Available, Soft State, and Eventual consistency), are gaining ground in the big data era, while SQL databases are left trying to keep up  ...  Acknowledgments: Author thanks the supervisor Zhao Shun Wang for all the understanding and encouragement.  ...

CadaML: A Modeling Language for Multi-Tenant Cloud Application Data Architectures

Assylbek Jumagaliyev, Yehia Elkhatib
2019 2019 IEEE 12th International Conference on Cloud Computing (CLOUD)  
In cloud applications, the data layer is often the prime candidate for multi-tenancy, and usually comprises a combination of different cloud storage solutions such as relational and non-relational databases  ...  As an alternative, we propose a domain-specific modeling language, CadaML, that provides concepts and notations to model a multi-tenant data architecture in an abstract way.  ...  Relational databases are expressed by SQL database. SQL-Partition of a relation database is classified according to partitioning schemes that were described in Section II-B.  ...
