... but there are still few and partial solu- tions. In general, given an information source, different translations can be defined for the same target model. In this work, we first identify gen- eral properties that “good” ... search. These techniques have been implemented in a tool for the man- agement of heterogeneous data models and some ...

... 666.47 KB Many problems in information integration rely on specifications, called schema mappings, that ... for both relational and nested data are well-known. In this work, we present a new formalism for schema mapping that extends these existing formalisms in two significant ways. First, our nested mappings allow for nesting and ...
