What are some effective data indexing techniques?

Effective data indexing techniques include B-trees, hash indexing, and bitmap indexing. Each has its own use cases.

Can you explain how B-trees work?

B-trees are balanced tree data structures that maintain sorted data and allow searches, sequential access, insertions, and deletions in logarithmic time.

What are the advantages of using hash indexing?

Hash indexing provides fast data retrieval by using a hash function to compute the address of the data, making it ideal for equality searches.

Are there any downsides to bitmap indexing?

Yes, bitmap indexing can be inefficient for high-cardinality data and may consume more space compared to other indexing methods.
