Using perspective schemata and a reference model for helping in the design of data integration systems
Valéria Magalhães Pequeno,

Sharing and integrating information across multiple autonomous and heterogeneous data sources has emerged as a strategic requirement in modern business. We deal with this problem by proposing a declarative approach based on the creation of a reference model and perspective schemata. The former serves as a common semantic meta-model, while the latter defines correspondence between schemata. Furthermore, using the proposed architecture, we have developed an inference mechanism which allows the (semi-) automatic derivation of new mappings between schemata from previous ones.
