Hi,
i want to ask you about exceptions and model tables as many to many relationship with junction table like below:
So specific CustomerTopoSysVersion can have multiple SystemVersions and each of SystemVersion can have multiple OSes.
But i have exceptions here.
Sometimes instead of CustomerTopoSysVersion --> SystemVersions --> OperatingSystems i can have
CustomerTopoSysVersion --> OperatingSystems (not every CustomerTopoSysVersion will have SystemVersion, sometimes i have to skip it)
How do you handle with this kind of situation?
Are you using some kind of artificial string for SystemVersion like "NoMatch" in junction table or something like that or you have another solutions?
Please help,
Jacek
