Create data model designs

As you add, remove, or delete entity and relationship types and their properties, and update visualization layouts, you can save your data model designs to the investigation. You can save multiple designs in one investigation. Additionally, you can view differences between a data model design and the current data model. Saved data model designs are available in the Catalog pane within the investigation. Data model designs can be edited, saved, and applied to the data model. You can export data model design files and import existing data model designs.

2. On the toolbar at the top of the data model designer, click the Save drop-down arrow and click Save As.

   The Save Data Model Design dialog box appears.

Import and export data model design files

Data model designs can be imported to an investigation from a file. After creating or modifying a design, you can export it to a data model design file. You can also drag a design file in your project onto another investigation in the same project or in a different project that is open in a second instance of ArcGIS Pro.

   Since the data model designs are stored with the investigation in the project, the design files that were imported are not saved in your project until the project has been saved.

Export a data model design

You can export an existing data model design file to your investigation.

1. If needed, save a data model design.
2. Browse to your investigation in the Catalog pane or the catalog view.
3. Double-click an investigation to see its contents.

Merge the data model with the design

You can compare a current data model of the knowledge graph with a data model design. You can merge a current data model with an existing data model design. You can choose how the differences are visualized in the data model designer. Types present in the design that do not exist in the data model can appear as a new item added and types deleted in the design, but still present in the data model, can appear as deleted .

1. Ensure the data model designer is open.
