Unit 2: Creating an Object Relationship Type

Step 1: Relationship Modeling for Wind Turbine and Wind Turbine Monitoring Application Type

During wind turbine operation, various metrics are connected and monitored through the app. Different monitoring applications are for different wind turbine equipment.

Here, we create a Many-to-Many relationship for the wind turbine object types and the monitoring application object types.

1. In the left navigation bar of the Data Catalog, click Object Type.

2. Click the New Object Type> New Object Relationship button.

3. On the New Object Relationship page, enter or select the following information:

   • Basic Information:
     • Type ID: enter Turbine_App_Relation
     • Description: enter mock Turbine_App_Relation for tutorial
     • Relationship: select ManyToMany
   • Relationship Configuration:
     • Type 1:
       • Type ID: select UD_EAM_Turbine
     • Type 2:
       • Type ID: select UD_APP
   

4. Click OK to complete the relationship creation between the wind turbine object type and the monitoring app object type.

Step 2: Relationship Modeling for Wind Turbine and Wind Turbine Station Data Types

Each wind turbine device corresponds to a different station. Here, we create a OneToMany relationship for the station type and wind turbine type.

1. In the left navigation bar of the Data Catalog, click Object Type.

2. Click the New Object Type> New Object Relationship button.

3. On the New Object Relationship page, enter or select the following information:

   • Basic Information:
     • Type ID: enter Site_Turbine__Relation
     • Description: enter mock Site_Turbine__Relation for tutorial
     • Relationship: select OneToMany
   • Configuration Relationship:
     • Type 1:
       • Type ID: select UD_site
     • Type 2:
       • Type ID: select UD_EAM_Turbine
   

4. Click OK to complete relationsship creation of the station type and wind turbine type.

After the object type relationship is created, in the category list on the Object Type function homepage, click View at the end of a specific relationship type row to view and edit its basic information.
