PORSCHE: Performance ORiented SCHEma mediation
Semantic matching of schemas in heterogeneous data sharing systems is time consuming and error prone. Existing mapping tools employ semi-automatic techniques for mapping two schemas at a time. In a large-scale scenario, where data sharing involves a large number of data sources, such techniques are not suitable. In this paper we present a method, which creates a mediated schema tree from a larg...

Semantic matching of schemas in heterogeneous data sharing systems is time consuming and error prone. Existing mapping tools employ semi-automatic techniques for mapping two schemas at a time. In a large-scale scenario, where data sharing involves a large number of data sources, such techniques are not suitable. We present a new robust mapping method which creates a mediated schema tree from a ...
متن کاملSchema Mediation and Query Processing in Peer
P2P Data Management Systems (PDMSs) allow the efficient sharing of data between peers with overlapping sources of information. These sources share data through semantic mappings between peers. In current systems, queries are asked over each peer’s local schema and then translated using the semantic mappings between peers. In this thesis we propose that a mediated schema can benefit PDMSs by all...
متن کاملSchema Mediation in Peer Data Management Systems
Intuitively, data management and data integration tools should be well-suited for exchanging information in a semantically meaningful way. Unfortunately, they suffer from two significant problems: they typically require a comprehensive schema design before they can be used to store or share information, and they are difficult to extend because schema evolution is heavyweight and may break backw...
