Abstract:
1. A computer-implemented method for schema mapping and data transformation, the method comprising the following steps performed by a processor: obtaining information associated with a conceptual model, wherein the conceptual model comprises at least one conceptual object; identifying a source model corresponding to a source schema and at least one source instance; receiving first mapping data for mapping a source attribute of the source model to a conceptual attribute of the conceptual model; generating, based on the first mapping data, a first mapping formula for transforming values associated with the source attribute into at least one value associated with the conceptual attribute; identifying a target model corresponding to a target schema and at least one target instance; and generating second mapping data for mapping the conceptual attribute of the conceptual model to a target attribute of the target model, based on the first mapping data and the first mapping formula, wherein:
