b+ tree
A B+ tree is a self-balancing tree data structure that provides efficient storage and retrieval of large amounts of data. It is primarily used in database systems and file systems. The B+ tree organizes data in the form of a multi-level index, enabling quick access to data items based on their keys. It maintains sorted order within each level and uses a set of rules to maintain balance, which ensures efficient searching and insertion/deletion operations. The "B+" in B+ tree refers to the properties of the tree, such as the minimum and maximum number of keys in each node.
