Types of Information Systems
There are many types of information systems that serve different purposes and functions. Some of the most common types of information systems are:
Transaction Processing Systems
A transaction processing system (TPS) is an information system that processes transactions that occur in an organization or a society. A transaction is an exchange or transfer of data or value between two or more parties. For example, a sale, a purchase, a deposit, a withdrawal, a reservation, a registration, a booking, a check-in, a check-out etc. A TPS records transactions in a database and ensures their accuracy, completeness, consistency, and timeliness. A TPS also generates reports and summaries of transactions for various purposes. A TPS is usually designed to handle high volumes of transactions efficiently and reliably. Some examples of TPS are point-of-sale systems, banking systems, airline reservation systems, hotel management systems, inventory management systems etc.
Management Information Systems
A management information system (MIS) is an information system that provides information to managers and other decision makers in an organization or a society. An MIS collects data from various sources, such as TPS, internal databases, external databases, surveys, interviews etc., and processes them into useful information that can support decision making, planning, controlling, organizing, and directing. An MIS also generates reports and dashboards that present information in a clear and concise manner. An MIS is usually designed to provide relevant and timely information that can help managers and decision makers achieve their goals and objectives. Some examples of MIS are accounting systems, budgeting systems, financial reporting systems, human resource management systems, marketing management systems etc.
Decision Support Systems
A decision support system (DSS) is an information system that helps users make decisions and solve problems in complex and uncertain situations. A DSS provides users with tools and techniques that can assist them in analyzing data and information, exploring alternatives, evaluating outcomes, and choosing the best option. A DSS also provides users with feedback and guidance that can improve their decision making and problem solving skills. A DSS is usually designed to be interactive and adaptable to user preferences and needs. Some examples of DSS are spreadsheet applications, simulation models, optimization models, expert systems etc.
Executive Information Systems
An executive information system (EIS) is an information system that provides information to senior executives and top managers in an organization or a society. An EIS collects data from various sources, such as MIS, DSS, TPS, external databases, news feeds, etc., and processes them into strategic information that can support executive decision making, planning, and visioning. An EIS also generates reports and dashboards that present information in a graphical and interactive manner. An EIS is usually designed to provide high-level and summarized information that can help executives and top managers monitor and control the performance, trends, opportunities, and threats of the organization or the society. Some examples of EIS are business intelligence systems, balanced scorecard systems, performance management systems, etc.
Expert Systems
An expert system is an information system that mimics the knowledge and reasoning of a human expert in a specific domain or field. An expert system consists of a knowledge base that stores facts and rules about the domain or field, and an inference engine that applies the rules to the facts to draw conclusions or make recommendations. An expert system also has a user interface that allows users to interact with the system and ask questions or seek advice. An expert system is usually designed to provide expert-level solutions or suggestions to users who may not have the expertise or experience in the domain or field. Some examples of expert systems are medical diagnosis systems, legal advice systems, financial planning systems, etc.
