1. A product comprising: a machine readable medium; and data mapping tool logic stored in the medium for execution by a processor, the data mapping tool logic comprising: an application view selection interface operable to obtain an application view selection supported by a target database; a database mapping mode selection interface operable to accept a mapping mode selection between multiple different mapping modes, where the multiple different mapping modes comprise an interactive mapping mode; mapping execution logic operable to: initiate, based on the mapping mode selection, execution of a data mapping analysis from intermediate staging tables to target database columns in the target database to determine an intermediate staging table selection for mapping the target database columns; mapping result analysis logic operable to determine whether a conflict exists between a first intermediate staging table and a second intermediate staging table, among the intermediate staging tables, for mapping the target database columns; a conflict resolution interface operable to obtain a manual conflict resolution input, when the mapping mode selection specifies the interactive mapping mode; and a data mapping document completion interface operable to report creation of a data mapping document based on the intermediate staging table selection.
