Deletion in B+ Tree
- Place and erase the required record from the leaf node.
- If removal results in underflow of a node borrow from a neighbouring node or merge two nodes.
- Propagate up to the root if needed.
Examples: Let us take a student database with records arranged according to their student IDs. The B+ tree structures these records leading to effective searches, insertions and deletions.
