Physical Data Organization and Indexing

Physical Data Organization and Indexing. Chapter 11. Access Path. Refers to the algorithm + data structure ( e.g., an index) used for retrieving and storing data in a table The choice of an access path to use in the execution of an SQL statement has no effect on the semantics of the statement
