What are some effective database indexing techniques?

There are several effective database indexing techniques, including B-trees, hash indexing, and bitmap indexing. Each has its own use cases.

Can you explain how B-trees work?

B-trees are a type of self-balancing tree data structure that maintains sorted data and allows for efficient insertion, deletion, and search operations.

What are the advantages of using bitmap indexing?

Bitmap indexing is particularly useful for columns with a limited number of distinct values, as it can significantly reduce storage space and improve query performance.

Are there any downsides to using hash indexing?

Yes, hash indexing can lead to issues with range queries and is not suitable for ordered data retrieval, as it does not maintain any order.
