How to idenify the relationship between two entities
i would like to know , how can we find the relationship between two entities. suppose consider Account to Contact , it is 1: M. we can identify this by seeing the Account detail Page Layout. Account Detail Page Layout contains Contact Child Layout which says that 1 Account has Many Contact. Similarly for Contact to Account it is 1: 1 we can say this by seeing that contatc page layout contai a field from account page layout.
Now my question is their any other way we can find relationship between two entities in Oracle CRM On demand. In Siebel we can say that if we have a join then it is 1: 1 or M : 1 and if we have a link then it is M : M or 1:M
