Information Systems is a term used to describe automated systems that collect, analyze and store information and data. Management Information Systems (MIS) has emerged with the understanding of the importance of information in managerial functions and decisions, and the application of the system approach to management in order to enable managers to access the right information at the right time and in the right channels. Management information systems are a system for managing interactive information aimed at facilitating management functions to optimize organizational activities in order to save time and money. With this system, a management control is provided on the information. The aim of the system; to obtain, analyze and analyze the information in a systematic manner and to provide the required user with timely, accurate, current and minimum uncertainty.

In this paper, examples of informations systems that are used frequently will be mentioned. There are three types of information systems that we use in our day to day activities. These are:

• DSS        : Decision Support System
• KMS        : Knowledge Management System
• TPS        : Transaction Process System

In other words, it is the use of available formulas to solve unstructured problems. It is designed to support decision making.
