Pattern based processing of XPath queries

Gerard Marks, Mark Roantree
2008 Proceedings of the 2008 international symposium on Database engineering & applications - IDEAS '08  
This paper describes a pattern based approach to XPath query processing, which permits the execution of a group of XPath location steps in parallel.  ...  The query process involves transforming XPath expressions to SQL which can be executed over our optimised query engine.  ...  This work presents a pattern based approach for optimising XPath queries by transforming a group of XPath location steps into SQL commands that can be executed in parallel.  ...

XML), and exploits tree-basedpatterns in expressing queries; the results of queries are also trees, thus providing meansto compose (conjoin) queries without requiring intermediate manipulations.  ...  Scenarios for industry-scale multi-paradigm modelling involve analysis,transformation, or fine-grained manipulation of models. These models are often treatedwholly or in part as trees (e.g.  ...  The key components of our approach are: (i) a common interchange format, (ii) a tree query metamodel, (iii) a query results metamodel, and (iv) an algorithm.  ...

Using Sensor Networks to Measure Intensity in Sporting Activities [chapter]

Mark Roantree, Michael Whelan, Jie Shi, Niall Moyna
2009 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
The deployment of sensor networks is both widespread and varied with more niche applications based on these networks.  ...  In wireless networks such as these, the requirement is for complex methods of data management in order to deliver more and more powerful query results.  ...  Their usage of constraints on the data streams provides a useful query mechanism with possibilities for optimisation.  ...

Kevoree Modeling Framework (KMF): Efficient modeling techniques for runtime use [article]

Fouquet Francois, Brice Morin, Erwan Daubert, Noël Plouzeau
2014 arXiv   pre-print
The creation of Domain Specific Languages(DSL) counts as one of the main goals in the field of Model-Driven Software Engineering (MDSE).  ...  In this paper, we identify several properties the generated tools must comply with to be usable in other domains than desktop-based software systems.  ...  Approach Directly inspired by the select operator of relational databases and by XPath [4] , KMFQL-PS defines a query syntax aligned with the MOF concepts.  ...

Towards automated provenance collection for runtime models to record system history

Owen Reynolds, Antonio García-Domínguez, Nelly Bencomo
2020 Proceedings of the 12th System Analysis and Modelling Conference on ZZZ  
In highly dynamic environments, systems are expected to make decisions on the fly based on their observations that are bound to be partial.  ...  Logging is essential to support explanations of behaviour, but it poses challenges.  ...  Reusability is also offered as the provenance graph conforms to a metamodel based on W3C PROV-DM [18] that is independent of the system's runtime metamodel.  ...

Novel mediator architectures for Grid information systems

Alexander Wöhrer, Peter Brezany, A. Min Tjoa
2005 Future generations computer systems  
Usability and integratability was an big issue during the design phase -so we decided to support a subset of the well known Structured Query Language (SQL) to formulate query against our global schema.  ...  This technical report presents a data integration system based on the wrapper-mediator approach, namely the Grid Data Mediation Service.  ...  Grid Query Evaluation Service (GQES): GQES instances are created by the GDQS based on the query plans generated by the query compiler, optimiser and scheduler.  ...

Towards user-centric concrete model transformation

2012 2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)  
Model transformations are an important part of Model Driven Engineering (MDE).  ...  This specification technique provides pragmatic barriers for users of model transformations and prevents them from adapting MDE technologies.  ...  This is due use of XPath addressing strings.  ...

Usage of metadata [article]

This new subset was called XPath. Although XPath is a subset of XSLT, it can also be used it on its own.  ...  The XML metamodel is also containment-based, and is therefore easily adapted to LOM.  ...  Storing the RDF triples in a central database, we were able to realize metadata based retrieval tasks even of a more complex kind with basic database operations.  ...
