Workload-based optimization of integration processes
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 1479–1480https://doi.org/10.1145/1458082.1458343The efficient execution of integration processes between distributed, heterogeneous data sources and applications is a challenging research area of data management. These integration processes are an abstraction for workflow-based integration tasks, ...

Transaction reordering with application to synchronized scans
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 1335–1336https://doi.org/10.1145/1458082.1458265Traditional workload management methods mainly focus on the current system status while information about the interaction between queued and running transactions is largely ignored. An exception to this is the transaction reordering method, which ...

View and index selection for query-performance improvement: quality-centered algorithms and heuristics
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 1329–1330https://doi.org/10.1145/1458082.1458261Selecting and precomputing indexes and materialized views, with the goal of improving query-processing performance, is an important part of database-performance tuning. The significant complexity of the view- and index-selection problem may result in ...

A step towards incremental maintenance of the composed schema mapping
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 173–182https://doi.org/10.1145/1458082.1458108Schema mapping plays a fundamental role in modern information systems. Mapping composition is an operator that combines a chain of successive schema mappings into a single schema mapping. By pre-computing the composed schema mapping, the system can ...

Integrating web query results: holistic schema matching
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 33–42https://doi.org/10.1145/1458082.1458090The emergence of numerous data sources online has presented a pressing need for more automatic yet accurate data integration techniques. For the data returned from querying such sources, most works focus on how to extract the embedded structured data ...

A language for manipulating clustered web documents results
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 23–32https://doi.org/10.1145/1458082.1458089We propose a novel conception language for exploring the results retrieved by several internet search services (like search engines) that cluster retrieved documents. The goal is to offer users a tool to discover relevant hidden relationships between ...

Minimum-effort driven dynamic faceted search in structured databases
CIKM '08: Proceedings of the 17th ACM conference on Information and knowledge managementPages 13–22https://doi.org/10.1145/1458082.1458088In this paper, we propose minimum-effort driven navigational techniques for enterprise database systems based on the faceted search paradigm. Our proposed techniques dynamically suggest facets for drilling down into the database such that the cost of ...
