Explain how B-Tree works

Can someone explain how B-Tree works and what are points and pitfals you need to figure out about that?

A B-Tree is a self- balancing, sorted, multi-way tree data structure that maintains sorted data and allows for efficient logarithmic time complexity for searches, insertions, and deletions.

• All leaf nodes must be at the same depth, ensuring the is balanced.
• Each node can contain multiple keys and multiple children, reducing tree height.
• Nodes are kept within a specific range of keys (order/degree) to prevent underflow or overflow.
• Ideal for disk-based storage and databases because it minimizes expensive I/O operations.
