Tables As Trees: Merging with Wildcards Using Tree Traversal and Pruning
... Because a tree structure is typically dynamic and can grow and shrink over time, programmers traditionally use dynamic memory allocation to store trees. The structure of a single node is determined by the programmer, and then nodes are created and destroyed on an as-needed basis during program run-t ...

Prefix Based Numbering Schemes for XML: Techniques
... designed to determine the parent-child relationship between two given nodes. The major advantages of bit-vector schemes are that (i) the decision process uses a bit comparison and runs in constant time, and (ii) the construction time is linear. However, bit-vector schemes are inappropriate for vario ...

Scapegoat and Splay Trees
... First let’s consider the simple case where we start with a perfectly-balanced tree, and we only want to perform searches and deletions. To get good search and delete times, we can use a technique called global rebuilding. When we get a delete request, we locate and mark the node to be deleted, but w ...

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.
