    1. COThank you for this quite complete answer. Your pn_before is a prefix sum such as the ones used in the Fenwick tree as far as I understand, which seems good to me. The only thing I'm not seeing clearly is about insert/delete: with a standard binary search tree, this is easy like you explained (you append the node, update parents prefix sum if on the left branch). This is fine. But, what about a balanced tree (e.g. a Red Black tree or anything else) on which we apply rotations and everything when inserting? Can we easily maintain these properties?

    2. COThank you for your answer and pointing me to threaded tree. That's interesting to get "following pages" easily once you find the right "starting page" indeed. But the problem is that I want to query pages not on the internal item Ids (e.g. T140, T150 or anything else) but rather on the Item index in the list. For example in my first example, T120 will be the 21st item (as there is a page P1 of 20 elements). So I want to be able to query an interval [20-29] which should return the elements [T120, ...]. I don't want to search for 120 directly. Hope I'm clear.

    3. COThank you for your comment. Actually I'd like to be able to search for a specific interval in a better way than O(length) because as the list of pages grows, the data structure will become linearly slower if I'm not mistaken.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
