What are B-trees? Explain with example.

### What are B-Trees?

A B-tree is a self-balancing search tree designed to maintain sorted data and enable efficient search, sequential access, insertion, and deletion operations. It is primarily used in database systems and file systems where data is stored on disk, as it minimizes the number of disk accesses required to locate a particular item. 

#### Key Characteristics of B-Trees:
1. Balanced Nature: All leaf nodes are at the same level.
2. Multiple Keys per Node: Each node can store multiple keys and have multiple child pointers.
3. Degree (Order) of the Tree: Determines the minimum and maximum number of keys and children a node can have.
4. Efficient Searching: The tree is kept shallow, reducing the height and improving access time.
5. Dynamic Structure: Supports insertion and deletion without restructuring the entire tree.

### Properties of B-Trees
