Interbase-KB: Integrating a knowledge base system with a multidatabase system for data warehousing

N. Bassiliades, I. Vlahavas, A.K. Elmagarmid, E.N. Houstis
2003 IEEE Transactions on Knowledge and Data Engineering  
This paper describes the integration of a multidatabase system and a knowledge-base system to support the data-integration component of a Data Warehouse.  ...  The multidatabase system integrates various component databases with a common query language, however it does not provide capability for schema integration and other utilities necessary for Data Warehousing  ...  These new clients have to be used in order to access the extended features of InterBase KB , like global integrated schema, updateable materialized views, purely object-oriented database programming language  ...

Enhancing Course Reusability through XML Schemas Integration

Aida Boukottaya
2003 Document Numérique  
In this paper, we present the FAVORITE project, which proposes and describes a novel strategy to integrate heterogeneous XML Schemas. Two main aspects are considered in our approach.  ...  Firstly, integration aims to facilitate access to multiple distributed structured courses by providing global views that abstract and unify the original course sources.  ...  For this it extends XQuery to manipulate XML Schemas with various integration operations like those used in relational and object-oriented databases.  ...

Challenges in Integrating Biological Data Sources

1995 Journal of Computational Biology  
To counter the increasing dispersion and heterogeneity of data, different approaches to integrating these data sources are appearing throughout the bioinformatics community.  ...  Some of these data sources are conventional databases implemented using database management systems (DBMSs) and others are structured files maintained in a number of different formats (e.g., ASN.l and  ...  ACKNOWLEDGMENTS This research was supported in part by DOE DE-FG02-94-ER-61923, NSF BIR94-02292 PRIME, ARO AASERT DAAH04-93-G0129, and ARPA N00014-94-1-1086.  ...

Using Signifiers for Data Integration in Rail Automation

Alexander Wurl, Andreas Falkner, Alois Haselböck, Alexandra Mazak
2017 Proceedings of the 6th International Conference on Data Science, Technology and Applications  
Unfortunately, current integration approaches mostly neglect uncertainties and inconsistencies in the integration process in terms of railway specific data.  ...  In Rail Automation, planning future projects requires the integration of business-critical data from heterogeneous data sources.  ...  We thank Walter Obenaus (Siemens Rail Automation) for supplying us with test data.  ...

GPU-Based PostgreSQL Extensions for Scalable High-Throughput Pattern Matching

Grant Scott, Matthew England, Kevin Melkowski, Zachary Fields, Derek T. Anderson
2014 2014 22nd International Conference on Pattern Recognition  
We have developed an extension framework to perform data block processing of large pattern data sets, using a stream processing design that results in global k-nearest neighbor matches.  ...  This framework was specifically designed to support pattern matching on GPU from within the database environment.  ...  These result tuples are critical to integrate the pattern matching within a database management system with heterogeneous data processing, such as relational or spatial operations.  ...

2009 Encyclopedia of Database Systems  
Some related work has been done on the problem of integrating a data warehouse with external data stored in XML [6] and in object-oriented [11] format, but just a few works have been devoted to the specific  ...  automatic matching of terms and the resolution of structural conflicts (see [8, 12] for surveys on these topics).  ...  SCIENTIFIC FUNDAMENTALS Since data warehouse interoperability can be considered a special case of the problem of database integration, general data reconciliation techniques can be often used.  ...
