Mergeable persistent data structures
... First, elements of old which have been removed from q2 are removed from q1. This is done without accessing these elements by using the push and pop values. In the same way, all elements of old which are still in q2 are removed. Then, q2 is concatenated at the end of q1 by adding a new node where the ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
