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 ...

Quadtree
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
