COMPONENTS OF MANAGEMENT INFORMATION SYSTEM
Input and output devices constitute the hardware components of MIS.
The programs and applications that convert data into machine-readable language are known as software.
Procedures are sets of rules or guidelines, which an organization establishes for the use of a computer-based information system.
The computer experts, managers, users, analysts, programmers, database managers, and many other computer professionals who utilize the computer-based information systems are the personnel in a management information system.

DECISION SUPPORT SYSTEM
Decision support systems (DSS) are a computer-based information system that supports business or organizational decision-making activities. DSS’s serve the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance. DSS’s include knowledge-based systems. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from a combination of raw data, documents, personal knowledge, or business models to identify and solve problems and make decisions. Typical information that a decision support application might gather and present are:
Inventories of information assets (including legacy and relational data sources, cubes, data warehouses, and data marts),
Comparative sales figures between one period and the next,
Projected revenue figures based on product sales assumptions.
As mentioned above, there are theoretical possibilities of building such systems in any knowledge domain. One example is the Clinical decision support system for medical diagnosis. Other examples include a bank loan officer verifying the credit of a loan applicant or an engineering firm that has bids on several projects and wants to know if they can be competitive with their costs. DSS is extensively used in business and management. Executive dashboard and other business performance software allow faster decision making, identification of negative trends, and better allocation of business resources. A growing area of DSS application, concepts, principles, and techniques is in agricultural production, marketing for sustainable development. For example, the DSSAT4 package, developed through financial support of USAID during the 80's and 90's, has allowed rapid assessment of several agricultural production systems around the world to facilitate decision-making at the farm and policy levels. There are, however, many constraints to the successful adoption on DSS in agriculture. DSS are also prevalent in forest management where the long planning time frame demands specific requirements. All aspects of Forest management, from log transportation, harvest scheduling to sustainability and ecosystem protection have been addressed by modern DSSs. A comprehensive list and discussion of all available systems in forest management is being compiled under the COST action Forays’ A specific example concerns the Canadian National Railway system, which tests its equipment on a regular basis using a decision support system. A problem faced by any railroad is worn-out or defective rails, which can result in hundreds of derailments per year. Under a DSS, CN managed to decrease the incidence of derailments at the same time other companies were experiencing an increase.
Clinical decision support system
Clinical decision support systems (CDSS or CDS) are interactive computer programs, which are designed to assist physicians and other health professionals with decision making tasks. A working definition has been...
