How Do Information Systems Work?

Information systems integrate human and technical components to collect, store, process and distribute the data needed by part or an entire organization. An information system can either be specialized or general.

A good example of a specialized information system is a database management system (DBMS). It allows users to freely analyze and organize data. Electronic spreadsheets also fall under this category.

Specialized information systems are specifically built to carry out particular processes and support specified analysis tasks. A management information system (MIS) is a special form of information system that outputs reports based on stored data, assisting enterprises to make informed decisions based on the analyzed data. Other types of specialized information systems include: decision support systems and operation support systems.
