thanks for your answer. I read the articles already when I had a question some days ago but they do not help me. All articles and information i find about section access contain mostly the same few information but i miss some real examples with some possible data models to be able to compare and try around.
Somehow i don't get this in my brain... Would I need a fake-fact-table which contains all possible combinations of values for all possible users? This can't be the right way, it would mess up storage, memory and performance, right? Also how would i be supposed to associate this fake-fact-table with my real tables, since there would be x of them?
