1. Clustered Index: A type of index that determines how data is physically stored in a table. Each table can have only one clustered index. 2. Non-Clustered Index: An index that stores the indexed columns along with a pointer to the actual data rows. Multiple non-clustered indexes can be created on a single table. 3. Primary Key Index (Clustered): A special kind of clustered index where the primary key columns are used as the basis for sorting and organizing the data in the table. 4. Unique Index: An index that ensures no duplicate values among its indexed columns. 5. Full-Text Index: Used to search textual data in a column or multiple columns.
