Implementing sub-types
Hello ,
I am urgently seeking to get clarification and a way forward to the above subject area.
I have a super-type entity called regulatory Incident and to that there are three sub-types; flooding, interuption and Low Pressure all have a 1:1 link with the super-type entity.
they all share same key. The person who mapped this into the Logical Data Model did from an object-orienated approach.
What are the critical things I need to know in trying to finalise the LDM??
should these be merged? Can it be implemented as it stands? What are the pre-conditions to merge?
Please help and I am wiling to provide further clearification if required.
