I'm currently working on an end of cycle project named: " Mapping an uml class diagram into a relational database model using the model-to-model transformation tool Henshin".
I've successfully been able to transform classes, attributs and 1..1 associations, however i'm facing a problem regarding the 1..N and N..N associations. the 1..N and N..N associations have different rules of transformation, but since the N..N association is a 1..N association in both ways (1->N and N<-1), Henshin isn't able to differentiate between the two rules and is executing for the N..N associations the rule of 1..N association twice !!
I don't know how to fix this probelm. I'm not very familiar with Henshin since i'm just a beginner. Thank you for reading and i hope some of you can help !
