- Transaction processing system
- Executive support system
Explanation of Solution
Management Information System (MIS) is a business function, like accounting, human resources, operations which moves information about people, products and processes across the company to facilitate decision making, and problem solving. MIS solves the issue with information silos.
Decision Support System (DSS) is needed to enable managers to get answers of unexpected and nonrecurring type of situation. It provides flexible tools for analysis that helps middle managers. DSS is used to analyses present data and find favorable alternate options for the problem. It must be noted that DSS only suggest solutions. It does not take decisions and the final decision-making is up to the decision maker.
Transaction processing system helps organization keep records of all transaction within and outside company. It also helps keep routine operations so there should be no lack or inefficiency in organization’s work.
