  2. B-tree - Wikipedia

    en.wikipedia.org/wiki/B-tree

    A B-tree insertion example with each iteration. The nodes of this B-tree have at most 3 children (Knuth order 3). All insertions start at a leaf node. To insert a new element, search the tree to find the leaf node where the new element should be added. Insert the new element into that node with the following steps:

  3. B+ tree - Wikipedia

    en.wikipedia.org/wiki/B+_tree

    The order or branching factor b of a B+ tree measures the capacity of interior nodes, i.e. their maximum allowed number of direct child nodes. This value is constant over the entire tree. For a b-order B+ tree with h levels of index: [citation needed] The maximum number of records stored is =

  5. 2–3–4 tree - Wikipedia

    en.wikipedia.org/wiki/2–3–4_tree

    2–3–4 trees are B-trees of order 4; [1] like B-trees in general, they can search, insert and delete in O(log n) time.One property of a 2–3–4 tree is that all external nodes are at the same depth.

  6. Tree (automata theory) - Wikipedia

    en.wikipedia.org/wiki/Tree_(automata_theory)

    A labeled tree formally defines a commonly used term tree structure. A set of labeled trees is called a tree language. A tree is called ordered if there is an order among the successors of each of its nodes. The above definition of tree naturally suggests an order among the successors, which can be used to make the tree ranked.

  7. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    Let T be a node of an ordered tree, and let B denote T's image in the corresponding binary tree. Then B's left child represents T's first child, while the B's right child represents T's next sibling. For example, the ordered tree on the left and the binary tree on the right correspond: An example of converting an n-ary tree to a binary tree

    Add solar superflares to the list of natural disasters of concern. Superflares are extremely strong solar flares – explosions with energies up to ten thousand times that of typical solar flares.

  9. Talk:B-tree - Wikipedia

    en.wikipedia.org/wiki/Talk:B-tree

    This is a fundamental requirement for the data-structure algorithms on B-tree to work. In particular then, a 2-3 tree is not a B-tree; it's algorithms are different than those of B-trees. The text currently uses 2-3 trees as a recurring example; those examples should be changed to refer to the 2-3-4-tree, the smallest example of a B-tree.
