What are some effective SQL database indexing strategies?

What are some effective SQL database indexing strategies?

Effective indexing strategies include using B-trees, bitmap indexes, and covering indexes to optimize query performance.

Can you explain how B-tree indexes work?

B-tree indexes maintain sorted data and allow searches, sequential access, insertions, and deletions in logarithmic time.

What are covering indexes and when should I use them?

Covering indexes include all the columns needed for a query, reducing the need to access the actual table, which speeds up performance.

Are there any downsides to using too many indexes?

Yes, too many indexes can slow down write operations and increase storage requirements, so it's important to balance them.
