What are the trade-offs of using indexes in SQL databases?
Using indexes can speed up data retrieval but may slow down data modification operations like INSERT, UPDATE, and DELETE.
Can you explain how indexes improve query performance?
Indexes allow the database to find rows faster by creating a data structure that points to the location of the data, reducing the search space.
Are there any downsides to having too many indexes?
Yes, too many indexes can lead to increased storage requirements and can slow down write operations due to the overhead of maintaining the indexes.
How do I decide which columns to index?
Consider indexing columns that are frequently used in WHERE clauses, JOIN conditions, or as part of ORDER BY statements.
