Generic Schema Mappings
Schema mappings come in different flavors: simple correspondences are produced by schema matchers, intensional mappings are used for schema integration. However, the execution of mappings requires a formalization based on the extensional semantics of models. This problem is aggravated if multiple metamodels are involved. In this paper we present extensional mappings, that are based on second or...
متن کاملReflection ideals and mappings between generic submanifolds in complex space
Results on finite determination and convergence of formal mappings between smooth generic submanifolds in C are established in this paper. The finite determination result gives sufficient conditions to guarantee that a formal map is uniquely determined by its jet, of a preassigned order, at a point. Convergence of formal mappings for realanalytic generic submanifolds under appropriate assumptio...
متن کاملGeneric schema mappings for composition and query answering
In this article we present extensional mappings, that are based on second order tuple generating dependencies between models in our Generic Role-based Metamodel GeRoMe. Our mappings support data translation between heterogeneous models, such as XML Schemas, relational schemas, or OWL ontologies. The mapping language provides grouping functionalities that allow for complete restructuring of data...
متن کاملSchema exchange: Generic mappings for transforming data and metadata
In this paper we present and study the problem of schema exchange, a natural extension of the data exchange problem in which mappings are defined over classes of similar schemas. To this end, we first introduce the notion of schema template, a tool for the representation of a set of schemas sharing the same structure. We then define the schema exchange notion as the problem of: (i) taking a sch...
متن کاملPlanar Harmonic Univalent and Related Mappings
The theory of harmonic univalent mappings has become a very popular research topic in recent years. The aim of this expository article is to present a guided tour of the planar harmonic univalent and related mappings with emphasis on recent results and open problems and, in particular, to look at the harmonic analogues of the theory of analytic univalent functions in the unit disc.
