A
highly unstructured decision is one where the objectives of the situation are
often conflicting, the alternatives available to the decision maker are
difficult to isolate or determine, and the effect of a particular course of
action or selection of an alternative carries with it a high degree of
uncertainty.

The data management
component of a DSS is where the activities associated with the retrieval,
storage and organization of the relevant data for the particular decision
context are managed.
Difficulty: Hard Reference: p. 9
