UB-tree

UB-tree stands for "universal b-tree". It is a type of tree data structure that is often used to store and organize data. A tree is a structure with nodes (or circles) connected by lines. In a UB-tree, each node can have more than one child, meaning they can connect to more than one other node. The UB-tree is particularly useful because it allows us to store and organize very large amounts of data in a way that is easy to search, update, and modify. To use a UB-tree, you must add or delete data from the tree in order to keep it organized.
