Hi
I have Client, Owner, and Staff entity, they all are persones!! with additional criteria...
Client
ID, FName, MName, LName
Owner
ID, FName, MName, LName
Staff
ID, FName, MName, LName
so Is there a concept of inheritance in RDBMS like SQL-Server-2005
if so how can I implement it.
At lease I will create a new Table called Person which include those attributes and create a 1-1 relationship between Person and those tables...what do you think.. Is that better or just complexing the design and why??
Thanks
