The mapping tab in the diagram helper makes it possible to define a grid of source and target attributes and define a mapping association between these attributes. It can be used for mapping in a layer (LDM or TDM) and for creating mappings between LDM and TDM. There are a number of extra functions and features:

• Load mappings is used to load the existing mappings in the grid after the source and target attributes are loaded
• Match names is a routine to create mappings between source and target attributes with the same name (useful for DataVault modeling)
• Load data is default active, when not active only the comboboxes in the grid are loaded and not the grid
• Map to target is default checked, when not check the data in the grid is loaded based on the source attributes (useful for creating mergers)
• Generate name when checked creates a mapping with the name of the attribute
• With connector stereotype you can define the stereotype of the association.
