Schema mapping and data transformation on the basis of a conceptual model

摘要

Systems and methods are provided for schema mapping and the transformation of data. In accordance with one implementation, a computer-implemented method is provided that comprises loading a conceptual model, wherein the conceptual model contains at least one conceptual object, loading a source schema and a source instance, converting the source schema and the source instance into a source model, and acquiring, from the user, at least one forward mapping usable to map at least a source attribute of the source model to a conceptual attribute of the conceptual model, wherein the forward mapping includes a mapping formula. Further, the method may include loading a target schema and a target instance, converting the target schema and the target instance into a target model, and reverse mapping at least one of conceptual attributes of the conceptual model to a target attribute of the target model based on the forward mapping and the mapping formula.
