11. An apparatus, comprising: a storage device; and a processor coupled to the storage device, wherein the storage device stores a program for controlling the processor, and wherein the processor, being operative with the program, is configured to: identify first mapping data for mapping values of a source attribute into at least one value of a conceptual attribute, the source attribute being associated with a source model, the conceptual attribute being associated with a conceptual model; generate, based on the first mapping data, suggested mapping formulas for transforming the source attribute values into the at least one conceptual attribute value, the suggested mapping formulas being associated with probability values indicative of a probability that the transformed source attribute values match the at least one conceptual attribute value; establish a corresponding one of the suggested mapping formulas as a first mapping formula, the first mapping formula being associated with a probability value that exceeds a predetermined value; generate second mapping data for mapping the conceptual attribute to a target attribute of a target model; and based on the second mapping data and the first mapping formula, generate a second mapping formula for transforming the conceptual attribute value into at least one value associated with the target attribute.
