Hi
Its basic question
My understanding about copy and Delta link is
Copy doesnot ahve direct relationship with source object (but it acts as a sibling) any changes done to spurce object does not affect target object.
Where as Delta link will have a parent child relation ship between source object bacially its a copy of source and inherits id properties. in case if i change source object does this affect target object, we can delete, add content to delta link target object.
let's say if i want to use standard quickpoll iView do i need to use copy or delta link similarly for other iviews, worksets, roles which one will be better.
