Index is a database structure that improves the speed of data retrieval. Types include clustered, non-clustered, and full-text.

• Index is a data structure that improves query performance by allowing faster data retrieval.

• Clustered index determines the physical order of data in a table.

• Non-clustered index is a separate structure that stores a copy of the indexed columns and a pointer to the actual data.

• Full-text index is used for text-based searches and allows for complex querie...read more
