However I would like to filter key attributes as dropdown from A, B, C and D to find results in BCD (because in the end I need BCDid). In BCD next to BCid and Did I can store of course Aid, Bid and Cid, and it would seem to me quite an easy workaround, however I know it's totally against db normalisation. Is there another, better way (with eager loading of course)? I've now this in
