Time for action – creating an alternate key for DeptEO

Currently, the DeptEO.xml file has Deptno as the primary key. We would add business validation that states that there should not be a way to create a duplicate of the department name that is already available. The following steps show how to create an alternate key:

  1. Go to the General section of the DeptEO.xml file and expand the Alternate Keys section. Alternate keys are keys that are not part of the primary key.
  2. Click on the little + icon to add a new alternate key.
  3. Move the Dname attribute from the Available list to the Selected list and click on the OK button.
