The stage process reads data from a landing table, cleanses the data, and moves the cleansed data into a staging table in the Hub Store. The

MDM Hub

uses the staging table as a temporary, intermediate storage in the flow of data from landing tables into base objects.

Mappings help the transfer and cleansing of data between landing and staging tables during the stage process. A mapping defines which landing table column the

MDM Hub

must use to populate a column in the staging table. A mapping defines the standardization and verification that the

MDM Hub

must perform before it populates a staging table.

The

MDM Hub

standardizes and verifies data by using the cleanse functions that you configure. Use cleanse functions for specialized cleansing functionality, such as address verification, address decomposition, gender determination, text casing, and white space compression. The output of the cleanse function becomes the input to the target column in the staging table.
