Hi Tomas,
i think its more like the other way around, id/parent is used for building tree etc. and nested sets only in some special cases. Regards, Frank Von: dev-general-boun...@lists.oxidforge.org [mailto:dev-general-boun...@lists.oxidforge.org] Im Auftrag von Tomas Liubinas Gesendet: Mittwoch, 18. Juli 2012 14:39 An: dev-general@lists.oxidforge.org Betreff: Re: [oxid-dev-general] Nested Sets and OXSORT Hi Joscha, Yes, technically category parent id and sorting information is not needed for nested set functionality, so this information is redundant and is probably never used when building the tree and selecting categories. However it could be used for more simple data import. It is easier to define child-parent relation over parent id field in 3rd party system and then import it to eShop. Parent id is also useful in cases when nested set values are screwed for some reason and you need to rebuild the tree completely.

The question is more like: Why do we have left+right although we use ParentID and Sorting? Isn't that a bit too redundant?

And the sorting becomes easier, because every category with oxparent = 'oxrootid' has oxleft=1 at the moment.
