Mapping is the process of aligning incoming data with a predefined format required by the destination system. It solves the challenge of inconsistent data structures between sources and destinations—something that often happens when different systems export data in varying formats. Mapping ensures that data is automatically interpreted, transformed, and organized to match the expected structure, using rules like one-to-one mapping, combining, splitting, and more. This eliminates the need for manual rework, reduces errors, and significantly speeds up the process of preparing data for import into the destination database.
