Defining a new Association relationship

Before you begin

You have a Talend Data Catalog Advanced Plus license edition.
You have been assigned a global role with the Application Administration capability.

Go to MANAGE > Metamodel then click START EDITING.
In the Object Types panel, select an object type from the list.
On the right side of the properties, click the Relationships tab.
Click the Add icon then select New relationship (association).
Select the Bi-directional check box to create a bi-directional relationship or clear the check box to create a uni-directional relationship.

Fill in the following fields.

Field	Description
END1 Object Type	Select an object type from the list, for example `Term`. Enter a source role name in the Name field, for example, `Has acronym`. Select the cardinality, for example `Many`. Type in a description.
END2 Object Type	Select an object type from the list, for example `Acronym`. If it is a bi-directional relationship: Enter a destination role name in the Name field, for example `Is Acronym for`. Select the cardinality, for example `Many`. Type in a description.
Participates in semantic flow	Click Yes to include this relationship in the usage and definition semantic flow lineage. By default, the option is set to No.

An association role name must be unique for the END1 and END2 objects.

To open the properties of the new relationship, expand the node of the parent object and click the relationship name in the Object types panel.
If necessary, reorder the relationships in the list using the Move Down or Move Up icon.
If necessary, remove a relationship type using the Remove selected relationships icon.
