## Explain ree database. Explain its common uses?

## Answer:

A tree is a data structure which resembles a hierarchical tree structure. Every element in the structure is a node. Every node is linked with the next node, either to its left or to its right. Each node has zero or more child nodes. The length of the longest downward path to a leaf from that node is known as the height of the node and the length of the path to its root is known as the depth of a node.

Common Uses:

- To manipulate hierarchical data

- Makes the information search, called tree traversal, easier.

- To manipulate data that is in the form of sorted list.

- To give visual effects for digital images using as a work flow by compositing them.
