A popular file structure supported by most dbmss because it provides good performance on both key search as well as sequential search. A btree file is a balanced, multiway tree. The most popular variation of the btree is the b+tree, in which all keys are redundantly stored in the leaf nodes. The b+tree provides improved performance on sequential and range searches. A btree can be used as a primary or secondary file structure.
