Data Domain Map
A data dictionary can be split into a set of logical data domains. A data domain map is used to visualize the dependencies between logical data domains.
Dependency links between domains are automatically deduced from the objects previously described in each domain of the map.
For more information on data dictionaries, see Data Dictionary.Creating a Data Domain Map
You can create a data domain map from the data dictionary it describes.
To create a (logical) data domain map in HOPEX Data Governance:
1. Click the Architecture > Data Dictionaries navigation menu.
In HOPEX Data Architecture, click the Dictionaries > Hierarchy navigation menu.2. In the edit area, under the hierarchy view, expand the Data Dictionaries folder.
3. Right-click on the data domain and select New > Data Domain Map.
The map appears in the tree.
To create the diagram of the data domain map:
1. Right-click the map and select New Diagram.
2. Select the diagram type Data Domain Map.
3. Click OK.
The diagram appears in the edit area.
Components of a Data Domain Map
You can add internal and external components to a data domain map.
The internal components are data domains that are part of the map scope (whether they belong to the owner package or not).
The external components are those used in the map but that are not part of the scope analyzed.
