Classification by System Objectives

• Transaction Processing Systems: Their objective is to process transactions in order to update records and generate reports, ie., to perform score-keeping functions.

• Decision Support Systems: Their objective is to support the managerial decisions. Usually, these systems are based on a model of the decision-making domain, and utilize techniques from management science, finance or other functional areas of business in order to build such models. These systems are also used often for attention-directing purposes, ie., for directing the attention of managers to a problematic aspect of operations.

• Expert Systems: These systems incorporate expertise in order to aid managers in diagnosing problems or in problem-solving.
