Don't Scrap It, Wrap It! A Wrapper Architecture for Legacy Data Sources

Mary Tork Roth, Peter M. Schwarz
1997 Very Large Data Bases Conference  
Garlic wrappers model legacy data as objects, participate in query planning, and provide standard interfaces for method invocation and query execution.  ...  To date, we have built wrappers for 10 data sources.  ...  In particular, Laura Haas spent many hours with us working out the details of the query processing interface.  ...

Domain-dependent information gathering agent

Aleksander Pivk, Matjaz Gams
2002 Expert systems with applications  
The major advantage of the agent is a semi-automatic creation of a wrapper around a particular site with few human interventions.  ...  We present a domain-dependent agent for information gathering. It can visit an arbitrary domain-related site by observing a user perform the first query.  ...  We would like to thank the CEO of the Employment Service of Slovenia, Mr J. Glazer.  ...

Bio-Broker: a tool for integration of biological data sources and data analysis tools

J. F. Aldana, M. Roldán-Castro, I. Navas, M. M. Roldán-García, M. Hidalgo-Conde, O. Trelles
2006 Software, Practice & Experience  
A first approach was based on wrappers, which act as interfaces for the data sources, translating their structure into a common model [3, 4] .  ...  Later, the focus moved to the use of mediators for encapsulating the knowledge needed for evaluating a query over multiple wrappers.  ...  We thank the reviewers for their comments and help towards the improvement of the paper.  ...

Optimizing high performance computing workflow for protein functional annotation

Larissa Stanberry, Bhanu Rekepalli, Yuan Liu, Paul Giblock, Roger Higdon, Elizabeth Montague, William Broomall, Natali Kolker, Eugene Kolker
2014 Concurrency and Computation  
With the rapid expansion of the protein sequence universe, the proposed workflow will enable scientists to annotate big genome data.  ...  The volume of protein data makes manual curation infeasible, whereas a high compute cost limits the utility of existing automated approaches.  ...  The authors are grateful to Elizabeth Stewart for critical reading of the paper. The feedback and comments from the anonymous reviewers are also much appreciated. This  ...

DAIMON

Constantinos V. Katsaros, Ioannis L. Niarhos, Vasilis Vassalos
2005 Proceedings of the 4th ACM international workshop on Data engineering for wireless and mobile access - MobiDE '05  
DAIMON is based on an extension of the mediator-wrapper architecture, where each node is a mediator of its own information and information from its neighbouring nodes.  ...  The implementation of the DAIMON system is also discussed.  ...  The use of a global schema known to all peers simplifies wrapper tasks: there is no need for general data model translations.  ...

Query processing in multistore systems: an overview

Carlyna Bondiombouy, Patrick Valduriez
2016 International Journal of Cloud Computing  
And the first RDBMSs too were built on top of a file system. For instance, the famous Ingres RDBMS [SKWH76] was implemented atop the Unix file system.  ...  In Section 3, we review the main query processing techniques for multidatabase systems, based on the mediator-wrapper architecture.  ...  Query-based Approach In the query-based approach, the wrappers support the same query capability, e.g. a subset of SQL, which is translated to the capability of the data source.  ...
