After database is loaded in HSAM which of the following operation becomes invalid?
D
Correct answer
Explanation
HSAM (Hierarchical Sequential Access Method) stores database records sequentially without hierarchical pointers. The GHNP (Get Hierarchical Next Parent) operation requires parent-child navigation capabilities that HSAM does not support. After loading a database in HSAM format, only sequential operations like GU (Get Unique), GN (Get Next), and GNP (Get Next Parent) remain valid.
