Answer / manjeet kumar
The disadvantages of a hierarchical database are:
·lack of flexibility (non-hierarchical relationships are
awkward to represent; redundancy may be required),
·poor performance for non-hierarchical accesses,
·lack of maintainability (changing relationships may
require physical reorganization of data).
