What are indexes, and what are the different types?..

Answer / nashiinformaticssolutions

Indexes improve query performance by speeding up data retrieval.
Types of Indexes:
1. Clustered Index: Sorts and stores data physically in the table.
2. Non-clustered Index: Creates a separate structure to store pointers to the actual data.
3. Unique Index: Ensures all values in a column are unique.
4. Composite Index: Includes multiple columns in the index.
