o Data management component – stores and maintains the information that you want your DSS to use
o User interface management component – allows you to communicate with the DSS Types of Decisions (Structured, Nonstructured, Recurring, Nonrecurring) o Structured decision – processing a certain information in a specified way so that you will always get the right answer

o Nonstructured decision – one for which there may be several “right” answers, without a sure way to get the right answer
o Recurring decision – happens repeatedly
o Nonrecurring (ad hoc) decision – one you make infrequently Artificial Intelligence, Geographic information System, Expert System, Swarm intelligence o Artificial intelligence, the science of making machines imitate human thinking and behavior, can replace human decision making in some instances
