In fact, it is technically implemented tool for recording, storing and disseminating linguistic expressions, and the conclusions from such expressions. It can systems.TYPES system information through the system can be divided into two basic forms1. ACTION SUPPORTSYSTEMSIt divided into
If the Transaction Processing System (TPS), business process or system work system2. MANAGEMENT SUPPORTSYSTEMIt divided into the following system information system (IMS) and a Decision Support System (DSS) and Executive Support (ESS) tool development SYSTEMThe DATA steps in development are part of information systems include: feasibility studies, design, testing, implementation, documentation. Trends in the computer system. “It is generally accepted that the necessary information for the smooth operation Modern business organizations use computer systems to obtain the desired information.

Imagine what could happen if the banking system failures due to some critical errors in the system, or if the health information system to give bad advice to patients.
