How can i create one-to-one relationship between two custom objects in salesforce.com.
Example: I have two custom objects having following details:
1) Employee (Name, PanCardNo)
I have gone through documents of salesforce, but i can able to find out only lookup (One-to-many raltionship) and master-detail relationship(many-to-many relationship).
Is there any way to create one-to-one relationship??
