What are Information Systems?
In its most basic form, an information system is a set of interconnected components that collect, process, store, and distribute information. Information systems come in different forms and serve various purposes, but they all have the same fundamental components. These components include hardware, software, people, data, and communication networks. Information systems can be classified into different categories, depending on how they are used within an organization.
Types of Information Systems
Below are the most common types of information systems:
Transaction Processing Systems (TPS)
TPSs are systems that process data resulting from day-to-day business transactions. Examples include sales transactions, payroll, and inventory management.
Management Information Systems (MIS)
MIS collects, stores, and processes data to produce information that managers can use to make decisions. This information is often presented in the form of reports, dashboards, or scorecards.
Decision Support Systems (DSS)
DSS is an information system that provides support for decision-making activities. DSS is designed to help users analyze data, identify trends, and make informed decisions.
Executive Information Systems (EIS)
EIS is a specialized information system designed to support senior managers’ decision-making activities. EIS provides easy access to critical information such as financial data and industry trends.
Real-life Examples
