An Information System (IS) is a coordinated set of protocols and components used to collect, store, and manage data within an organization. Its primary purpose is to support decision-making, coordination, control, analysis, and visualization in an enterprise.
Components of an Information System
Hardware
Physical devices and equipment such as servers, computers, and networking devices that constitute the backbone of an IS.
Software
Programs and applications that process and manage data. This includes system software, application software, and database management systems (DBMS).
Data
A core component, data encompasses both raw figures and processed information used by an organization.
Procedures
Protocols and instructions governing the operation and use of the IS, ensuring that data is processed efficiently and accurately.
People
Users who interact with the IS, including IT professionals, end-users, and management.
Types of Information Systems
Transaction Processing Systems (TPS)
