    Welcome to FL. Please visit the Help centre and especially the How do I ask a good question? section. The title of your question "What is the difference between 'de' and 'des' in French?" will not be answered here, we only answer questions about one specific problem. Your question could be improved if you want a satisfying answer: – the use of de or des in all your sentence fragments could depend on context so if you want to know why they are correct you must provide more context;

  • – the reasons for choosing de or des might be different for each pair of fragments, so it might be better to ask different questions for each pair. You say you are confused, if you can say why it, might help getting a useful answer.

Les profils des clients. Cette phrase signifie que cela porte sur le profil de chaque client. Un profil par client. 5 clients = 5 profils.

Les profils de clients. Celle-ci signifie que un profil peut correspondre à plusieurs clients. 5 clients ont 2 profils (ex: Le profil acheteur compulsif et le profil acheteur raisonné).

Raisonnement similaire pour ces phrases: Les données des comportements des clients. Le comportement de chaque client individuel est observé.

Les données de comportements des clients. Cette phrase signifie plus un comportement global (moyenne de tous les clients) qui serait observé à travers plusieurs données (temps passé, panier moyen, réceptivité aux offres).
