How does a B-tree work?

Can you explain how a B-tree works?

Sure! A B-tree is a self-balancing tree data structure that maintains sorted data and allows for efficient insertion, deletion, and search operations.

What are the main properties of a B-tree?

B-trees have several key properties: they are balanced, each node can have multiple children, and all leaf nodes are at the same level.

How does a B-tree handle insertions?

When inserting, a B-tree finds the appropriate leaf node and adds the new key. If the node exceeds its maximum capacity, it splits into two nodes.

Can you give an example of a B-tree insertion?

Certainly! If you have a B-tree of order 3 and you insert keys 10, 20, and 30, the first two keys will be in one node, and inserting 30 will cause a split.

What are the advantages of using a B-tree?

B-trees are efficient for disk-based storage systems, as they minimize disk reads and writes, making them ideal for databases.
