Getting Started with InfoSphere Data Architect

8.1.2 Further managing naming standards with mapping models
Chapter 8 – Model Mapping and Discovery 145
You can use a glossary or naming model to discover relationships between source and target schemas.
You learned about glossary models in Chapter 3 of this book. The naming rules that you defined earlier in
the data design process can be used to identify the relationships between different schemas.
Note:
You will not perform the steps outlined in this section. They are provided for reference only.
You already created a glossary model to track the names of entities, tables, and other data objects in
your data models. You could use this glossary model to ensure that all data models conform to the
naming standards that you have defined for your organization. If the mapping model discovery cannot
correctly determine which objects should be mapped, then perhaps some of these objects are out of
compliance.
To determine if models are in compliance with naming standards with a mapping model:
1. Open the Enterprise Naming Standard window to attach a naming model to the mapping model:
a. Open the mapping editor by opening an existing mapping model.
b. Right-click in the mapping editor.
c. Select Discover Relationships -> Enterprise Naming Standard. The window opens.
2. Select the schema to which you want to attach a naming standard.
3. Click the Add button next to the Naming model list pane. The Select Naming Model Files window
opens.
4. Select a glossary model (with the file extension of .ndm) and click OK.
5. Repeat the steps above for any remaining schemas, then click Finish.
6. Discover the relationships based on the best fit:
a. Right-click in the mapping editor and select Discover Relationships -> Find Best Fit. The
Discover Relationships window opens.
b. Select the schemas for which you want to discover the relationships, then click Finish.
The models are analyzed, and the workbench determines which data objects should be related in the
mapping model.
7. Approve or reject the mappings.
8. Create new mappings if necessary.
9. Save your work.
