Which indexing method allows for faster retrieval of data?
Correct Answer: B-Tree Indexing
Step 1: Understand what indexing means. Indexing is a way to organize data to make it easier and faster to find.
Step 2: Learn about different types of indexing methods. There are several methods, but we will focus on B-Tree indexing.
Step 3: Know what a B-Tree is. A B-Tree is a type of data structure that keeps data sorted and allows for efficient insertion, deletion, and retrieval.
Step 4: Understand the balanced structure of a B-Tree. This means that all leaf nodes are at the same level, which helps in keeping the search time consistent.
Step 5: Compare B-Tree indexing with other methods. B-Tree indexing is generally faster because it reduces the number of comparisons needed to find data.
Step 6: Conclude that B-Tree indexing is preferred for faster data retrieval due to its efficient structure.
