Hi

I have the following tables

ClassGroups \ Class \ student

I would like to create a rules table that will apply from the top to the bottom So for example I can apply global rules that would apply to all class groups - then each classgroup can have rules that override for any student in that class - then any class can apply the rules - down to the individual student who can have his/her own rules

I guess my question is like this - I would like to take a student and determine the highest level rules that apply

Can I do this with inheritance?

Do you think you could post a more detailed example about a specific instance. I'm just not sure what exactly you are looking for.
