B trees , B+ trees with examples

Question

Accepted Answer

B trees and B+ trees are data structures used for efficient storage and retrieval of data in databases.

B trees are balanced trees with a variable number of child nodes per parent node. They are commonly used in databases to store large amounts of data.
B+ trees are a variant of B trees where all data is stored in the leaf nodes, and the internal nodes only contain keys. They are commonly used in databases for indexing.
B+ trees are more efficient than B trees for range queries and sequential access.
Example: In a database of student records, a B+ tree can be used to index the records by student ID, allowing for efficient retrieval of records based on ID.
Example: In a database of sales transactions, a B tree can be used to store the transactions in order of date, allowing for efficient retrieval of transactions within a certain date range.
