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
