Method for deriving data mappings and data aliases

摘要

This invention describes a computer application system and method for automatically deriving data mappings by processing stored data mappings. Derived data mappings are system generated data mappings. The system comprises a plurality of stored data mappings, a data mapping report generator, and a data mapping tool. Heretofore, data mappings were created by human analysis of data from two or more sources to determine the relationship between data fields. This time consuming process has been eliminated by the present invention. The derived data mappings may be stored for later use or provided to other system programs. The derivation may be performed at various levels of abstraction. Derived data mappings that should not be used are also identified.
