Question

The solution to deal with nonunique search keys added an extra attribute to the search key. What effect could this change have on the height of the B+-tree?

Expert Solution

Step 1

B+ Tree

A B+- tree is used mainly for multi-level hierarchical indexing. The B+ trees only store the data points at the leaf nodes of the tree compared with the B- Tree, thus improving the accuracy and speed of the search process.

The nonunique search key was given a further attribute of the search key. What effect this update could have on the height of the B+ tree.

Data archives are stored using leaves.
It is stored in the Tree's inner nodes.
If a goal key value is smaller than the internal node it is followed by the point to the left.
If the main value of the target is higher or equal to the internal node, then this argument is followed only on the right side.
There are at least two kids in the root.
Key is used mainly to help search the right leaf.
For growing and decreasing in a tree, B+ Tree uses a "fill factor"
Numerous keys can easily be put on the memory page in B + trees since they have no internal node-related data.
Therefore, the tree data on the leaf node can easily be obtained.
The tree requires only a linear pass, since all the leaf nodes of the B+ tree are bound to one another, to complete a full search of all elements.
