Information Systems

Information systems are the software and hardware systems that support data-intensive applications.

So, the purpose of an information system is to turn raw data into useful information that can be used for decision making in an organization.

Typical Components of Information Systems

While information systems may differ in how they are used within an organization, they typically contain the following components:

• Hardware: Computer-based information systems use computer hardware, such as processors, monitors, keyboard and printers.
• Software: These are the programs used to organize, process and analyze data.
• Databases: Information systems work with data, organized into tables and files.
• Network: different elements need to be connected to each other, especially if many different people in an organization use the same information system.
• Procedures: These describe how specific data are processed and analyzed in order to get the answers for which the information system is designed.

History

The first large-scale mechanical information system was Herman Hollerith’s census tabulator. Invented in time to process the 1890 U.S. census, Hollerith’s machine represented a major step in automation, as well as an inspiration to develop computerized information systems
