ColDef Table
The Data Warehouse uses the OLE DB provider for Commerce Server Core Systems to map logical entities to physical tables in the database. The ColDef table in the profiles database contains metadata about mapping column definitions. Data is updated in this table when you change a profile definition by using the Commerce Server Manager or when you change a Data Warehouse schema. The ColDef table might not be present in your installation of Commerce Server Core Systems.
You should not modify the ColDef table.
