Data mapping is the creation of a mapping element between two separate data models for use of data integration. Uses include data transformation, data migration, data mediation, identification of data relationships.

Data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks including:

  • Data transformation or data mediation between a data source and a destination
  • Identification of data relationships as part of data lineage analysis
  • Discovery of hidden sensitive data such as the last four digits social security number hidden in another user id as part of a data masking or de-identification project
  • Consolidation of multiple databases into a single data base and identifying redundant columns of data for consolidation or elimination
  • Data federation
  • Semantic mapping for use in ontologies, taxonomies, master data management, etc.
