The Business Data Mapper allows users to create or transform information into a digestible form in which the best results can be achieved. Data mapping itself is the process by which two distinct data models are created and a link between these models is defined. Its main function is the process of creating data element mappings between different data models. Data mapping is used as a first step for a wide variety of data integration tasks. It also plays a vital role to consolidate multiple databases into a single data source and in identifying redundant columns of data for consolidation or elimination.
