Insertion in B+ Tree Create records at appropriate leaf level. The height of B-Trees is kept low by putting maximum possible keys in a B-Tree node. (Minor) disadvantage of B+-trees: Extra insertion and deletion overhead, space overhead. Leaf nodes also contain an additional pointer, called the sibling pointer, which is used to improve the efficiency of certain types of search. As with a B-tree the root node may have between 2 and m = 4 children and hence between 1 and 3 keys and every other node may have between dm=2e = 2 and m = 4 children and hence between 1 and 3 keys: Each leaf node also has a value (some data) associated to its key.
