When split the child, move a key from the child to its parent x. Than mid key in the child, then set x as first part of the child. If the child is full, split it and change x to point to one of the two parts of the child. If the child is not full, change x to point to the child. If x is leaf and having space for one more info then insert a to x.įind the child of x that is going to be traversed next. Nodes in the B tree do not store pointers or any metadata except for the pointers to internal node children (while the B+ tree leaf nodes store a pointer to. Algorithm Beginįunction insert() to insert the nodes into the tree: Here is a C++ program to implement B tree of order 6. It is basically a self-balancing tree data structure that maintains sorted data and allows sequential access, searches, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children.
