Hi,



I have this conceptual model:



I have a type employe and each employe can be an InternEmploye or a 
Freelancer so I have a total-and-exclusive specialisation.



I would like to know how I should translate this into relational 
database tables.



if it were in a programming language like C++ it would be inheritance. 
How can I simul that in a relational database.



I hope my english is understandable,



Thanks in advance for your help



Mathieu Pagé
