Step 3. Create a Supplier Entity and Relate it to the Supplied Product Entity
In this step, you will create a Data entity called Supplier and relate it to the Supplied Product entity.
1. Create a Data entity called Supplier.

2. Create the following elements for the Supplier entity:
|
Element Name |
Data Type |
Field Name |
|
Supplier number |
ID Number |
iiiSUPNUM |
|
Supplier name |

iiiSUPNAM |
3. Set Supplier Number to be the identifying element.
4. Close the Entity Elements window.
Note that, because the Product Entities Abstraction is active, the Supplier Entity has been added to the Product Entities Abstraction automatically.
5. Create a Mandatory Join (must refer to) relationship between Supplied Product and Supplier by connecting a relate shape source to the Supplied Product entity and then target to the Supplier entity.
Leave its Descriptive Prefix blank.
6. The model diagram should now appear something like this:
