Questions & Answers

Q: What is the significance of the order of a B-Tree in construction?

The order of a B-Tree determines the maximum number of children each node can have, leading to the capacity of keys a node can store, essential for balanced tree structure.

Q: How does split and propagate help maintain the balance of a B-Tree?

Split and propagate ensures that new keys are inserted in leaf nodes first, splitting full nodes to propagate median values up the tree, maintaining balance and adherence to capacity rules.

Q: Why is it crucial to have leaf nodes at the same level in a B-Tree?

Having leaf nodes at the same level in a B-Tree ensures balanced search operations, optimizing retrieval speed and storage efficiency.

Q: How does the split and propagate process address the issue of node capacity constraints?

Split and propagate ensures that when a node reaches full capacity, it is split into two nodes with equal keys, propagating the median value up the tree to maintain balance.
