USING ER/STUDIO > COMMON TASKS
ER/Studio automatically includes relationships between objects if related objects are part of the submodel. You can
edit the submodel to include or exclude specific relationships. When you add a relationship, ER/Studio automatically
includes the corresponding parent table in the submodel definition.
1 On the Data Model Window or Data Model Explorer, select one or more objects to include in the submodel.
TIP: CTRL-click to select multiple objects.
2 Click Model > Create Submodel.
3 In the Create Submodel dialog, enter a name for the submodel.
4 From the list of objects, CTRL-click to select the objects to add to the submodel and then press the right arrow to
add the selected objects to the submodel.
5 Click OK to create the submodel.
Once you are finished creating a submodel, ER/Studio adds the submodel to the Data Model Explorer and
displays the model in the Data Model Window.
The following describe options that require additional explanation:
Edit Submodel tab
• Click Select Related Objects to add parent and child entities and dependent views or procedural logic.
• If you select Inherit Objects Added to Nested Submodels, any objects you later add to submodels nested within
the model or submodel will automatically be also added to the model.
Attributes tab
Lets you choose which attributes of the entities selected on the Edit Submodel tab to include in the submodel.
Definition tab
Enter or edit a definition for the submodel.
Attachment Bindings tab
Bind an external piece of information, or attachment to the submodel. You can also remove an attachment from
an object, override an attachment binding’s default value, or change the position of a bound attachment. To
override the value of the attachment you have moved to the Selected Attachments grid, double-click the Value
field of the target attachment. ER/Studio opens the Value Override Editor or a list depending on the attachment
datatype. Attachments are created in the Attachments folder of the Data Dictionary. For more information, see
Attaching External Documents to the Data Model.
Security Information tab
Displays the current security information as defined in the Data Dictionary. You can add or edit security reporting
information in by double-clicking the field you want to change. To set the model-wide default value for a property,
go to the Data Dictionary tab and expand the Data Security Information node. For more information, see
Enforcing Security Using Data Security Types and Properties.
Notes
• If you select a submodel to add to the new submodel, then all objects belonging to the source submodel will be
added to the new submodel.
• Deleting an object from a submodel does not delete the object from the Main model unless you select the Delete
from Model option in the Delete dialog.
• Once you have created a submodel, you can add objects to it by right-clicking an object in the main model or in
another submodel and then selecting Apply to Submodel(s) from the shortcut menu. In the dialog that appears
you can select which submodels to add the object to.
